The Repentance of an Apostate Who Denies an Obligation

Question:
If a person testifies that there is no god but Allah, he does not enter Islam. And if a person testifies that there is no god but Allah but refuses to testify that Muhammad is the Messenger of Allah, he does not enter Islam. Yes. The repentance of an apostate, and the Islam of every disbeliever, is that he testifies that there is no god but Allah and that Muhammad is the Messenger of Allah. And if his disbelief was by denying an obligation or the like, his repentance, along with the two testimonies, is his acknowledgment of what he denied.

Answer:
If a person’s apostasy was due to denying something of the known rulings of the religion that are known by necessity, it is not sufficient for him to merely testify that there is no god but Allah and that Muhammad is the Messenger of Allah, because before that he was testifying that there is no god but Allah and that Muhammad is the Messenger of Allah; he did not deny the two testimonies. Therefore, his acknowledgment of what he denied must be added to them. So his repentance consists of two things: a general matter, which is the two testimonies, and a specific matter, which is his acknowledgment of what he denied. His acknowledgment of what he denied. Yes.
