What is the ruling on a person who doubted whether his action was an act of disbelief (kufr) or a sin, and repented with two intentions: the intention that it was a sin, and the intention that it was disbelief, so he pronounced the Shahada and performed ghusl? Is he considered a Muslim? And does he need to renew his Islam if it later becomes clear that his action was disbelief? And what should he do if it becomes clear that his action was a sin?
Sincere repentance, fulfilling its conditions, is sufficient. A Muslim does not need to renew his Islam or offer another repentance if it becomes clear to him that what he committed was a sin and not an act of disbelief (kufr). Increasing seeking forgiveness and repentance in general is a prescribed act, for Allah loves those who repent, accepts their repentance, and forgives them.
