As salamu alaykum, Could the learned brothers explain the viewpoint of Ahlus Sunnah when it comes to repenting from kufr? The main questions I have are 1. Is it necessary to say the Shahadah to enter fold of Islam again? Or is simply doing tauba in the heart enough? 2. What can a person do if he has doubts over his iman? (For example, the person knows the correct creed and is aware of what constitutes kufr. But he thinks he has had a kufr belief before, or have done or said kufr before) 3. Does such a person constantly renew their faith and is this valid? Jazak Allah
