14.2 Apostasy in Islam (Riddah)

If becoming a Muslim can occur through a simple, sincere declaration of faith, what happens if a person later changes their mind?

Leaving one’s religious faith is known as apostasy, or riddah in Arabic.

In this case, apostasy refers to a Muslim who consciously and intentionally rejects Islam after having accepted it. This may involve openly renouncing the faith, adopting another religion, or expressing beliefs that are understood to contradict core Islamic teachings.

This topic has been widely discussed in Sharia, theology, and history, and it remains one of the most debated and sensitive issues within Islam today.

While the Qur’an repeatedly mentions apostasy (e.g., 2:217, 3:90, 16:106), it does not prescribe a specific worldly punishment. Instead, it describes consequences in the afterlife and emphasizes that “there is no compulsion in religion” (2:256).

As a result, Sharia largely relies on various Hadith for its stance on apostasy. A frequently cited hadith states, “Whoever changes his religion, execute him.”

In many historical cases, apostasy was associated with political betrayal or rebellion against the community, particularly when religion and governance were closely connected. Thus, some classical legal rulings treat apostasy as a serious offense with legal consequences.

Some scholars argue that these rulings applied specifically to cases of “political apostasy” (such as treason or desertion to enemy forces during wartime) rather than to a private change of belief.

Many modernist and reformist scholars emphasize the Qur’anic principle of freedom of conscience and argue that any worldly punishment for a personal change in faith is un-Islamic.

Qur’an 4:137 describes individuals who believe, then disbelieve, then believe again—a cycle that would be impossible if the first act of apostasy required execution.

However, several Islamic countries today maintain that apostasy can be punishable by death under specific conditions, particularly when it is public and associated with defiance or destabilization of the community. These rulings are typically subject to evidence, due process, and, in some interpretations, opportunities for repentance.

Such laws are reported in countries including Iran, Saudi Arabia, Afghanistan, Mauritania, Brunei, and Yemen, while in others, such as Nigeria and Somalia, they may exist in certain regions or under specific legal systems.

Sudan, historically one of the most active enforcers, abolished the death penalty for apostasy in 2020.

Views and laws regarding apostasy vary widely across Muslim-majority countries. Some countries maintain laws that penalize apostasy or related actions, while others do not enforce such laws or have moved toward broader protections for religious freedom. In some places, social consequences, such as family rejection or community pressure, are more significant than legal ones.

In Module 15, we will look more closely at Islam and political authority, including Sharia in: Saudi Arabia, Iran, Turkey, Pakistan, and Indonesia.
