3.3.1 Tawḥīd in the Qur’an

Centrality of Tawḥīd in the Qur’an

Tawḥīd is the heart of the Qur’an. Every major theme in the Qur’an, whether stories, laws, or promises of reward and punishment, ultimately returns to affirming the Oneness of Allah, worshipping Him alone, and rejecting all forms of shirk. Allah introduces His Book as guidance for those who are conscious of Him, and that guidance begins with Tawḥīd.

"Alif Lām Mīm. This is the Book about which there is no doubt, a guidance for the muttaqīn."
(Qur’an 2:1–2)

Those who are truly God conscious are described first and foremost by their unseen belief in Allah, His revelation, and the Hereafter. This unseen belief rests on Tawḥīd.

"Those who believe in the unseen, establish prayer, and spend out of what We have provided for them."
(Qur’an 2:3)

The Qur’an’s Call to Worship Allah Alone

The most repeated message of the Qur’an is a clear and direct call to single out Allah in worship and to abandon all rivals and partners. This is the explicit summary of the mission of every messenger, and the Qur’an reminds humanity of this core truth again and again.

"And We certainly sent into every nation a messenger, [saying], 'Worship Allah and avoid tāghūt.'"
(Qur’an 16:36)

The Qur’an does not merely command worship, it defines the correct object of worship. Worship is for Allah alone. When Allah mentions the purpose of human and jinn creation, it is described as worship directed only to Him.

"And I did not create the jinn and mankind except to worship Me."
(Qur’an 51:56)

This worship is exclusive. No one shares with Allah in divinity, in right to be prayed to, or in deserving acts of devotion, such as duʿā, fear, hope, and reliance. The Qur’an states in a short and comprehensive chapter:

"Say, 'He is Allah, [Who is] One,
Allah, the Eternal Refuge.
He neither begets nor is born,
nor is there to Him any equivalent.'"
(Qur’an 112:1–4)

This concise surah refutes all claims of partners, children, likeness, or equals for Allah, and is one of the clearest summaries of Tawḥīd in the Qur’an.

Tawḥīd ar-Rubūbiyyah in the Qur’an

The Qur’an constantly reminds people that Allah alone is the Lord, Creator, and Sustainer of all things. It presents this reality as something even many disbelievers instinctively admit, while failing to draw the correct conclusion in worship.

"If you asked them, 'Who created the heavens and the earth and subjected the sun and the moon?' they would surely say, 'Allah.' Then how are they deluded?"
(Qur’an 29:61)

Allah draws attention to creation, provision, life, and death to establish that He alone is in control. The Qur’an asks:

"Is there any creator other than Allah who provides for you from the heaven and the earth? There is no deity except Him, so how are you deluded?"
(Qur’an 35:3)

By repeatedly asking such rhetorical questions, the Qur’an teaches that recognizing Allah as Lord is a rational and natural conclusion. This recognition is not enough by itself unless it leads a person to worship Allah alone. Yet it is the starting point and foundation. The Qur’an links the management of the universe and the decree of all affairs to Allah alone:

"Unquestionably, His is the creation and the command. Blessed is Allah, Lord of the worlds."
(Qur’an 7:54)

This verse joins together creation and command, which shows that the One who creates has the sole right to command and legislate, and no one can share this authority with Him.

Tawḥīd al-Ulūhiyyah in the Qur’an

The central struggle described in the Qur’an between the prophets and their peoples was not about the existence of a Creator, but about worship directed exclusively to Him. The Qur’an presents the call of many prophets in these exact terms.

"And to ʿĀd [We sent] their brother Hūd. He said, 'O my people, worship Allah, you have no deity other than Him. Then will you not fear Him?'"
(Qur’an 7:65)

"And to Madyan [We sent] their brother Shuʿayb. He said, 'O my people, worship Allah, you have no deity other than Him.'"
(Qur’an 7:85)

This formula runs throughout the Book. Worship is treated as a right of Allah. Assigning any act of worship to another, whether a prophet, angel, saint, idol, or anything else, is condemned as injustice and falsehood.

"And [mention] when Luqmān said to his son while he was instructing him, 'O my son, do not associate anything with Allah. Indeed, shirk is a great injustice.'"
(Qur’an 31:13)

The Qur’an also shows Tawḥīd al Ulūhiyyah through promises and consequences. It states that safety and guidance in this world and the next belong to those who purify their faith for Allah.

"They who believe and do not mix their belief with injustice, those will have security, and they are [rightly] guided."
(Qur’an 6:82)

The Prophet ﷺ explained that "injustice" in this verse refers to shirk.

The Prophet ﷺ recited: "They who believe and do not mix their belief with injustice…" and said, "It is not as you think. It is shirk. Have you not heard what Luqmān said, 'Indeed shirk is a great injustice'?"
(Ṣaḥīḥ al Bukhārī)

The Qur’an thus links true belief with purification of worship from all partners and rivals.

Tawḥīd al‑Asmāʾ waṣ‑Ṣifāt in the Qur’an

The Qur’an introduces Allah to humanity by His Names and Attributes, so that people can know Him, love Him, and worship Him with understanding. It states that to Allah belong the most perfect and beautiful Names.

"And to Allah belong the best names, so invoke Him by them, and leave [the company of] those who practice deviation concerning His names. They will be recompensed for what they have been doing."
(Qur’an 7:180)

The Book affirms attributes of majesty and perfection for Allah, while completely denying any similarity between Him and His creation.

"There is nothing like unto Him, and He is the Hearing, the Seeing."
(Qur’an 42:11)

In numerous passages, the Qur’an combines the mention of Allah’s Names with reminders of His actions, in order to connect knowledge of Him with submission and hope. For example:

"Allah, there is no deity except Him, the Ever Living, the Sustainer of [all] existence."
(Qur’an 2:255)

"He is Allah, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Giver of security, the Overseer, the Exalted in Might, the Compeller, the Superior. Exalted is Allah above whatever they associate with Him."
(Qur’an 59:23)

By reading such verses, the believer is taught how to address Allah by His Names, and how to avoid any distortion, denial, or false analogy in describing Him.

The Qur’anic Rejection of Shirk

The Qur’an is very strong and clear in its condemnation of associating partners with Allah. It presents shirk as the only unforgiven sin if a person dies without repentance, and the greatest contradiction to the very purpose of revelation and existence.

"Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And whoever associates others with Allah has certainly fabricated a tremendous sin."
(Qur’an 4:48)

Shirk is frequently presented in the Qur’an as a form of ignorance, injustice, and loss. Those who direct supplication or sacrifice to others besides Allah are reminded that these so called deities possess nothing.

"And they worship besides Allah that which neither harms them nor benefits them, and they say, 'These are our intercessors with Allah.' Say, 'Do you inform Allah of something He does not know in the heavens or on the earth?' Exalted is He and high above what they associate with Him."
(Qur’an 10:18)

Allah exposes the weakness of these rivals in powerful images.

"O mankind, a parable is presented, so listen to it. Indeed, those you invoke besides Allah will never create [as much as] a fly, even if they gathered together for that purpose. And if the fly should steal away from them a [tiny] thing, they could not recover it from him. Weak are the pursuer and pursued."
(Qur’an 22:73)

The Qur’an describes the regret of those who practiced shirk when they see the reality in the Hereafter.

"Then they will be told, 'Call your partners.' And they will call them, but they will not respond to them, and they will see the punishment. If only they had been guided."
(Qur’an 28:64)

Through these verses, the Qur’an aims to cut off all roots of associating partners with Allah, whether in explicit idol worship or more subtle forms of dependence and fear toward created beings.

Tawḥīd and the Covenant with Humanity

The Qur’an presents Tawḥīd not as a foreign idea, but as a deep truth planted within human nature. It refers to a covenant taken from the children of Adam that affirms the Lordship of Allah.

"And [mention] when your Lord took from the children of Adam from their loins their descendants and made them testify of themselves, [saying to them], 'Am I not your Lord?' They said, 'Yes, we have testified.' [This] lest you should say on the Day of Resurrection, 'Indeed, we were of this unaware.'"
(Qur’an 7:172)

This primordial acknowledgment supports the Qur’anic description of Tawḥīd as something that fits sound human nature. The Prophet ﷺ said:

"Every child is born upon the fiṭrah, then his parents make him a Jew, or a Christian, or a Magian."
(Ṣaḥīḥ al Bukhārī, Ṣaḥīḥ Muslim)

The Qur’an’s call to Tawḥīd is therefore a call to return to the original, uncorrupted disposition that recognizes the One Lord and seeks Him alone.

Tawḥīd through Signs in Creation

One of the most common methods the Qur’an uses to teach Tawḥīd is to point repeatedly to the signs in the heavens and the earth, in the alternation of night and day, and in the creation of the human being. These signs are presented as clear evidence of the One who created and manages all affairs.

"Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding.
Who remember Allah while standing, sitting, and lying on their sides, and give thought to the creation of the heavens and the earth, [saying], 'Our Lord, You did not create this aimlessly; exalted are You; then protect us from the punishment of the Fire.'"
(Qur’an 3:190–191)

In such passages, the Qur’an ties reflection on the universe to worship and humility. The believer is not meant to stop at admiration of nature, but to move from the sign to the One who placed that sign. Another example states:

"And of His signs is the creation of the heavens and the earth and the diversity of your languages and your colors. Indeed in that are signs for those of knowledge."
(Qur’an 30:22)

By highlighting order, harmony, and wisdom in creation, the Qur’an shows that the Creator must be one, perfect in knowledge and power, and free of any partner or rival.

Tawḥīd through Revelation and Law

The Qur’an does not restrict Tawḥīd to matters of belief about creation. It also affirms Allah’s Oneness in command, legislation, and judgment. The One who is the only creator is also the only lawgiver whose right it is to be obeyed above all others.

"The command is for none but Allah. He has commanded that you worship none but Him. That is the correct religion, but most of the people do not know."
(Qur’an 12:40)

In this verse, worship and command are connected. To surrender to Allah in worship implies surrender to His judgment and law. The Qur’an also criticizes those who treat their religious authorities as deities by following them in altering what Allah has made lawful and unlawful.

"They have taken their scholars and monks as lords besides Allah, and [also] the Messiah, the son of Mary. And they were not commanded except to worship one God, there is no deity except Him. Exalted is He above whatever they associate with Him."
(Qur’an 9:31)

This shows that obedience in contradiction to Allah’s law, when taken as absolute and unquestioned, can become a form of hidden shirk. True Tawḥīd requires recognizing Allah’s ultimate authority and weighing every other authority against His revelation.

Tawḥīd and the Stories of the Prophets

The Qur’an narrates the stories of many prophets, but beneath the different contexts and people, their core message is the same. Each prophet’s struggle centers on calling to Tawḥīd and opposing shirk. The Qur’an summarises the belief common to all messengers:

"And We did not send before you any messenger except that We revealed to him that, 'There is no deity except Me, so worship Me.'"
(Qur’an 21:25)

The story of Ibrāhīm عليه السلام is a clear example. He debated with his people about their worship of idols, the stars, the moon, and the sun, guiding them step by step to the truth that none of these can be a true god.

"Indeed, I have turned my face toward Him who created the heavens and the earth, inclining toward truth, and I am not of those who associate others with Allah."
(Qur’an 6:79)

Every prophetic story in the Qur’an includes this call to abandon false gods and turn to Allah alone. Even when social or political issues are mentioned, they are tied back to the fundamental question of who deserves obedience and worship.

Tawḥīd and Accountability in the Hereafter

The Qur’an connects Tawḥīd to the reality of the Last Day. It teaches that success in the Hereafter depends on meeting Allah while affirming His Oneness and free of shirk. Deeds, no matter how many, are ruined if they are based on associating partners with Allah.

"And it was already revealed to you and to those before you that if you should associate [anything] with Allah, your work would surely become worthless, and you would surely be among the losers."
(Qur’an 39:65)

The Qur’an also describes how sincere Tawḥīd is a cause for Allah’s grace and entrance into Paradise.

"Indeed, those who have said, 'Our Lord is Allah' and then remained steadfast, the angels will descend upon them, [saying], 'Do not fear and do not grieve but receive good tidings of Paradise, which you were promised.'"
(Qur’an 41:30)

In another passage, Allah connects the firmness of this word of Tawḥīd to a safe outcome.

"Allah keeps firm those who believe, with the firm word, in worldly life and in the Hereafter."
(Qur’an 14:27)

The "firm word" is the statement of Tawḥīd that the believer lives by and dies upon. The Qur’an teaches that those who reject Tawḥīd will find all their excuses cut off on the Day of Judgment.

"Then on the Day of Resurrection you will deny each other and curse each other, and your refuge will be the Fire, and you will not have any helpers."
(Qur’an 29:25)

This constant linking of Tawḥīd with final accountability is meant to make belief in Allah’s Oneness a living, practical reality, not a mere idea.

Sincerity and Purifying Religion for Allah

One of the most frequent phrases in the Qur’an about worship is that it must be done "sincerely" for Allah. This sincerity is a direct expression of Tawḥīd, since it means cutting off all hopes from creation and placing them in the Creator.

"And they were not commanded except to worship Allah, [being] sincere to Him in religion, inclining to truth, and to establish prayer and to give zakāh. And that is the correct religion."
(Qur’an 98:5)

In another powerful verse, Allah commands the Prophet ﷺ to declare his worship free of all shirk.

"Say, 'Indeed, my prayer, my sacrifice, my living and my dying are for Allah, Lord of the worlds. No partner has He. And with this I have been commanded, and I am the first of the Muslims.'"
(Qur’an 6:162–163)

The Prophet ﷺ explained that even subtle desires to be seen by people can threaten this purity of worship.

The Prophet ﷺ said, "The thing that I fear most for you is the minor shirk." They said, "O Messenger of Allah, what is the minor shirk?" He said, "Showing off."
(Musnad Aḥmad)

The Qur’an’s constant insistence on sincerity aims to protect Tawḥīd from visible and hidden corruptions, and to make every action a step closer to Allah alone.

The Qur’anic Promise and Hope for the People of Tawḥīd

Alongside its firm warnings against shirk, the Qur’an fills the hearts of the people of Tawḥīd with hope and reassurance. Allah promises His nearness, His response to supplications, and His mercy for those who turn to Him alone.

"And when My servants ask you concerning Me, indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me and believe in Me that they may be guided."
(Qur’an 2:186)

The Qur’an also mentions that those who purify their worship are under Allah’s special care.

"Unquestionably, [for] the allies of Allah there will be no fear concerning them, nor will they grieve. Those who believed and were fearing Allah."
(Qur’an 10:62–63)

The people of Tawḥīd are described as those whom Allah will grant firmness in life and on the Day of Judgment, whose sins He will forgive, and whom He will admit into gardens beneath which rivers flow. All of this is ultimately built on a single foundation, recognizing and living by the Oneness of Allah as taught by the Qur’an.
