The Seriousness of Speaking About Faith
Judging the faith of a Muslim is among the heaviest matters in Islam. It concerns a person’s relationship with Allah, their place in the Muslim community, and their status in this life and the next. For this reason, the Qur’an and Sunnah strongly warn against speaking lightly about who is a believer and who is a disbeliever.
Allah praises those who submit outwardly and inwardly, and He forbids Muslims from making claims about others’ inner states without clear evidence.
“O you who have believed, avoid much suspicion. Indeed, some suspicion is sin. And do not spy or backbite each other.”
(Qur’an 49:12)
The Prophet ﷺ explained that accusing a Muslim of disbelief without right is extremely dangerous:
The Prophet ﷺ said: “If a man says to his brother, ‘O disbeliever,’ then surely it returns to one of them.”
(Ṣaḥīḥ al‑Bukhārī)
This hadith shows that takfir declaring someone a disbeliever is not a small error. It is a word that can return to the one who spoke it, if the accused is not truly a disbeliever in the sight of Allah.
Declaring a Muslim to be a disbeliever is among the gravest statements. A person must never do it casually, emotionally, or without clear knowledge and evidence.
The General Rule: Whoever Manifests Islam Is Treated as a Muslim
Islam deals with people based on their outward statements and actions, not on hidden thoughts. The Prophet ﷺ accepted people’s Islam when they said the Shahadah, even if others doubted their sincerity.
The Prophet ﷺ said: “I have been commanded to fight the people until they say, ‘None has the right to be worshipped but Allah.’ Whoever says, ‘None has the right to be worshipped but Allah,’ his wealth and his life are protected from me except by right of Islam, and his reckoning is with Allah.”
(Ṣaḥīḥ al‑Bukhārī and Ṣaḥīḥ Muslim)
This hadith shows two important principles. First, anyone who plainly enters Islam is treated as a Muslim. Second, the final judgment of their heart is with Allah, not with other people.
The Qur’an also forbids Muslims from judging someone as a disbeliever merely because they think their intention is not sincere.
“And do not say to one who gives you [a greeting of] peace, ‘You are not a believer,’ seeking the goods of worldly life…”
(Qur’an 4:94)
This verse was revealed about a man who greeted Muslims with the greeting of Islam to show his faith, but was wrongly killed because someone thought he only did that to protect his life. Allah condemned this act, and through it taught the Ummah to accept outward signs of Islam and leave the inner state to Him.
The basic rule is: Anyone who clearly shows Islam by testifying the Shahadah, praying toward the qiblah, and living as a Muslim is to be treated as a Muslim, unless an agreed‑upon, clear proof shows otherwise.
The Danger of Hastiness in Takfir
Takfir means to judge that a person or group is outside of Islam. Throughout history, Muslims have seen many problems when people rushed to takfir without knowledge. The Qur’an describes the believers as people of justice and careful speech, not of haste and harsh accusation.
“O you who have believed, if there comes to you a disobedient one with information, verify it, lest you harm a people out of ignorance and become, over what you have done, regretful.”
(Qur’an 49:6)
If Allah commands us to verify simple news, then how much more careful must we be before making a judgment that can remove a person from Islam.
The Prophet ﷺ warned that wrongful takfir harms the one who pronounces it:
The Prophet ﷺ said: “Any man who says to his brother, ‘O disbeliever,’ then it surely returns upon one of them.”
(Ṣaḥīḥ Muslim)
Scholars understood from this that the tongue must be controlled, and that it is safer to remain silent and leave the matter to the scholars and judges rather than to speak without proof.
It is forbidden to accuse a Muslim of disbelief due to anger, personal disputes, or differences in opinion on matters where scholars have allowed disagreement.
The Difference Between Major Kufr and Sinful Actions
In previous chapters, the concepts of faith and disbelief are explained in detail. Here, we focus only on how this relates to judging individuals.
Islam teaches that there is a difference between:
- The type of action
- The person who does it
Some actions are indeed acts of disbelief in themselves, such as openly mocking Allah or the Qur’an, or knowingly denying what is known of Islam by necessity. However, moving from this general ruling to saying that a particular person is a disbeliever requires conditions and careful study.
A Muslim may fall into a serious sin, or even an act which in itself could be disbelief, yet not be judged personally as a disbeliever if certain things are present, such as ignorance, misunderstanding, or acting under pressure.
Allah speaks of those who were forced to say a word of disbelief, but whose hearts remained firm in faith.
“Except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment.”
(Qur’an 16:106)
This verse clearly separates between the outward word and the inward state. It shows that the inner reality of a person’s faith matters, and that not every outward act means that the person has truly left Islam.
Not every sin, nor every wrong statement, means that a Muslim has become a disbeliever. The scholars distinguish between the ruling on an action and the ruling on a particular person.
Conditions and Barriers in Takfir
The scholars of Islam mentioned that before declaring an individual Muslim to be outside of Islam, certain conditions must be fulfilled and certain barriers must be absent. This topic belongs to advanced study in creed and law, so here we only mention it briefly in relation to judging others.
Among what they considered were issues like:
Clear proof from the Qur’an and Sunnah that the specific belief or action is disbelief in itself, with no serious disagreement among qualified scholars.
The person’s knowledge and understanding, whether the proof has reached them clearly.
Whether the person acted out of ignorance, mistake, misinterpretation, or under compulsion.
Because of these complexities, the scholars repeatedly warned that takfir of individuals is not a task for common Muslims, but for those deeply grounded in knowledge and for the proper Islamic authorities, and even they must be very cautious.
Allah says: “And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight, and the heart, about all those [one] will be questioned.”
(Qur’an 17:36)
This verse covers every type of speech made without knowledge, and takfir is among the most serious of these.
Takfir of specific individuals is a matter for qualified scholars and lawful authorities, not for ordinary Muslims. Speaking without knowledge about such matters is itself a major sin.
The Role of Scholars and Islamic Authorities
Islamic law gives responsibilities to different members of the community. Scholars interpret revelation, judges apply it in courts, and rulers protect society and maintain justice. Ordinary Muslims are not charged with making legal rulings on their own, especially in issues as sensitive as takfir.
The Qur’an directs believers to return difficult issues to those with knowledge and authority.
“And when there comes to them information about [public] security or fear, they spread it around. But if they had referred it to the Messenger or to those of authority among them, then the ones who can draw correct conclusions from it would have known about it...”
(Qur’an 4:83)
By analogy, matters which affect the safety, honor, and status of Muslims in society should also be returned to those who have the tools of knowledge and judgment.
The Prophet ﷺ warned about people who speak about religion without knowledge.
He ﷺ said: “Allah does not take away knowledge by snatching it away from the people, but He takes away knowledge by taking away the scholars, until when no scholar remains people will take ignorant ones as leaders. They will be asked, and they will give religious rulings without knowledge. They will go astray and will lead others astray.”
(Ṣaḥīḥ al‑Bukhārī)
This hadith applies strongly to those who declare takfir without training or guidance. When unqualified people start labeling others as disbelievers, the result is misguidance, division, and harm.
When confused or disturbed by another Muslim’s belief or practice, one must not judge their faith. Instead, seek clarification from reliable scholars and recognized Islamic centers, and observe good manners.
Unity, Mercy, and the Limits of Judgment
Islam commands Muslims to preserve unity, avoid splitting the community, and treat each other with mercy. Hastily declaring fellow Muslims as disbelievers destroys unity and causes deep harm.
Allah describes the believers as brothers in faith.
“The believers are but brothers, so make settlement between your brothers. And fear Allah that you may receive mercy.”
(Qur’an 49:10)
The Prophet ﷺ taught that the life, property, and honor of a Muslim are sacred and must be protected.
He ﷺ said in the Farewell Sermon: “Indeed, your blood, your property, and your honor are sacred to you, like the sanctity of this day of yours, in this month of yours, in this land of yours.”
(Ṣaḥīḥ al‑Bukhārī)
Labeling someone a disbeliever opens the door for others to treat them as if these protections are removed. This is why Islamic law makes such a judgment very rare and extremely restricted.
Allah also reminds us that He alone knows what is in the hearts.
“He knows what is within the heavens and earth and knows what you conceal and what you declare. And Allah is Knowing of that within the breasts.”
(Qur’an 64:4)
We judge only by what is clearly apparent and leave the inner reality to Him. This balance preserves both justice and mercy.
The heart of a Muslim is not for people to judge. We judge only what is clear and outward, apply the most merciful reasonable interpretation, and leave secrets of the heart to Allah.
Avoiding Extremes in Takfir
History has shown two harmful extremes regarding takfir.
One extreme is to make takfir very easily. Some groups in the past, such as the Khawārij, used to declare Muslims disbelievers for sins or disagreements. The Prophet ﷺ described them in harsh terms because they misused religious texts and harmed the Muslims.
He ﷺ said about them: “They recite the Qur’an but it does not go beyond their throats. They pass through Islam as an arrow passes through the target.”
(Ṣaḥīḥ al‑Bukhārī)
This description warns against using verses and hadith without understanding, in ways that lead to aggression against other Muslims.
The other extreme is to deny that disbelief exists at all, or to refuse to apply the clear labels that Allah and His Messenger have given to certain beliefs and actions. Islam is a clear religion with clear boundaries. Both exaggeration and neglect are blameworthy.
The balanced path is to affirm what Allah and His Messenger affirmed, and to deny what they denied, while respecting the rules and conditions that scholars have laid down. The individual believer’s role is usually not to pronounce final judgments, but to follow guidance and preserve their own faith.
Both extremes are wrong: declaring Muslims disbelievers without right, and denying the reality of disbelief that Allah has spoken about. The safe path is to follow revelation with knowledge and humility.
Practical Guidelines for Ordinary Muslims
For a beginner in Islam, it is important to know how to act when hearing controversial statements or seeing strange practices among Muslims.
First, remember that misguidance, sin, or even innovation does not automatically equal disbelief. There are many levels of wrong, and only some of them reach the level of kufr.
Second, focus on your own belief, worship, and character. These are the matters that you will be definitely asked about.
“O you who have believed, upon you is [responsibility for] yourselves. Those who have gone astray will not harm you when you have been guided to the right path. To Allah is your return all together, then He will inform you of what you used to do.”
(Qur’an 5:105)
Third, if you are troubled by another Muslim’s words or actions, ask trustworthy scholars. Do not spread accusations, and do not pass judgments on the person’s faith.
Fourth, guard your tongue. The Prophet ﷺ taught that controlling the tongue is a path to safety.
He ﷺ said: “Whoever believes in Allah and the Last Day, let him speak good or remain silent.”
(Ṣaḥīḥ al‑Bukhārī and Ṣaḥīḥ Muslim)
Silence is often safer than speaking without knowledge, especially in matters as serious as accusing someone of disbelief.
For ordinary Muslims, the correct practice is: avoid pronouncing takfir, avoid sharing accusations, ask reliable scholars when confused, and concentrate on strengthening your own īmān.
Hope, Fear, and Leaving Judgment to Allah
Belief in Allah includes belief in His ultimate justice and wisdom. Every human being will stand before Him on the Day of Judgment. There, every matter of hidden faith or disbelief will be made clear.
“Indeed, to Us is their return. Then indeed, upon Us is their account.”
(Qur’an 88:25‑26)
A Muslim lives between hope and fear. We hope that Allah will forgive our mistakes and the mistakes of other Muslims, and we fear for ourselves that we may fall into what displeases Him. This attitude protects the heart from arrogance and harshness toward others.
The Prophet ﷺ taught us to focus on our own shortcomings rather than looking for the faults of others.
He ﷺ said: “Blessed is the one who is kept busy by his own faults from the faults of the people.”
(Reported by al‑Bazzār; authenticated by some scholars)
By remembering our own need for mercy, we become less eager to deny mercy to others.
In summary, judging the inner faith of Muslims and declaring takfir is an area surrounded by warning, caution, and strict conditions. The believer’s path is to affirm the clear teachings of Islam, respect the unity and safety of the Muslim community, and leave final judgment of individuals to Allah and to those whom He has given knowledge and authority.
Guarding the tongue from wrongful takfir, preserving the honor and safety of Muslims, and leaving ultimate judgment to Allah are essential parts of sincere belief in Him.
