Is the repentance of an apostate who apostatized and then increased in disbelief accepted? What is the evidence for the acceptance of repeated repentance from an apostate? And will Allah remove hypocrisy from the hypocrite's heart if he supplicates for that?

The repentance of an apostate is accepted by Allah Almighty, even if their apostasy is repeated. This is the view of the majority of scholars among the Hanafis and Shafi'is, the well-known opinion among the Malikis, and one of the two opinions of Ahmad ibn Hanbal.

As for the verses, such as: ﴿Indeed, those who disbelieved after their belief and then increased in disbelief – never will their repentance be accepted, and those are the astray.﴾ [Al 'Imran: 90], and ﴿Indeed, those who believed then disbelieved then believed then disbelieved then increased in disbelief – never will Allah forgive them, nor will He guide them to a way.﴾ [An-Nisa: 137], scholars have interpreted them to mean that the non-acceptance of repentance occurs in the following cases: 1. At the approach of death. 2. When persisting in disbelief and not abandoning it. 3. The interpretation that Allah will not forgive them, meaning He will not conceal their sins but will expose them. 4. It indicates the unlikelihood of their repentance and obtaining forgiveness, because their hearts have been corrupted by disbelief, and it does not mean that their repentance is unacceptable if they are sincere.

The narration from Ibn Abbas, stating that the verse ﴿Indeed, those who disbelieved after their belief and then increased in disbelief – never will their repentance be accepted﴾ was revealed concerning a group of people who embraced Islam, then apostatized, then embraced Islam again, then apostatized; this narration was deemed weak by Al-Hafiz Ibn Hajar and Al-Suyuti. The correct view is that the verse was revealed concerning a man from the Ansar who embraced Islam, then apostatized and joined polytheism, then regretted it and sent to inquire about his repentance. So the verse was revealed: ﴿How shall Allah guide a people who disbelieved after their belief... Except for those who repent thereafter and reform, for indeed, Allah is Forgiving and Merciful.﴾ [Al 'Imran: 86-89]. Imam Al-Tabari interpreted it as referring to the Jews who disbelieved in the Prophet Muhammad (peace be upon him) and persisted in their disbelief.
