The Ruling on Declaring a Muslim a Disbeliever

Praise be to Allah, and peace and blessings be upon the Messenger of Allah.

The hadith mentioned is hasan (authentic/good). It was narrated by Ibn Hibban and others, and was graded as hasan by a number of scholars, including Shaykh al-Albani. Its meaning is a strong warning against hastily accusing Muslims of disbelief (kufr) or polytheism (shirk) without justification.

This meaning is supported by the statement of the Prophet Muhammad ﷺ:

"If a man says to his brother, 'O disbeliever,' then one of them will indeed deserve that description. If the accused is as he said, then it is true of him; otherwise, it returns to the one who made the accusation."

This demonstrates the grave danger of declaring someone a disbeliever without knowledge or clear evidence.

However, this warning does not apply to someone who describes as disbelief or polytheism an act that Islamic law has already established to be disbelief or polytheism based on authentic evidence. Rather, it applies to the person who unjustly or without proof accuses a Muslim of being a disbeliever or a polytheist. Whoever says to a Muslim, "You are a disbeliever" or "You are a polytheist," while that person is innocent of such accusations, has committed a grave sin.

On the other hand, if a person commits a statement or action that Islamic law classifies as disbelief or polytheism, it is permissible—and indeed necessary—to clarify the ruling regarding the action itself by saying, "This act is shirk," or "This statement is kufr," because explaining the rulings of Islamic law is an obligation. Doing so is not included in the warning mentioned in the hadith.

As for judging a specific individual to be a disbeliever or a polytheist, Ahl al-Sunnah wa al-Jama'ah have established strict principles. Such a judgment is not permissible unless the conditions for takfir have been fulfilled and all valid impediments have been removed. Among the most important of these conditions are:

• That the person has been presented with the authentic Islamic evidence (the proof has been established).
• That they know their statement or action contradicts the teachings of Islam.
• That they are not excused due to ignorance, a valid misunderstanding or interpretation, coercion, or other recognized impediments.

For this reason, the scholars distinguished between judging an act and judging the person who commits it. An act may indeed constitute disbelief or polytheism, while the individual who committed it is not declared a disbeliever until the Islamic proof has been clearly established against them and all recognized impediments have been removed.

Accordingly, a person who calls others to Tawhid (the Oneness of Allah) and warns against practices such as worshipping graves or seeking help from the dead may explain, when supported by Islamic evidence, that these actions constitute shirk. However, they should not hastily declare specific individuals to be disbelievers until the required Islamic conditions have been fulfilled.

In summary: The hadith is authentic in its meaning and serves as a serious warning against accusing Muslims of disbelief or polytheism without right. If an act or statement is proven by Islamic evidence to be disbelief or polytheism, its ruling should be clarified. However, declaring a specific person to be a disbeliever is only permissible after the Islamic proof has been established, all the conditions for takfir have been fulfilled, and all recognized impediments have been removed.

And Allah knows best.
