What is the ruling on the imamate of a man who commits many sins in private, repents, and then returns to them? Should he abandon the imamate until he abstains from his sin?

If a person is qualified for the imamate, such as being the most eloquent of those present and the most knowledgeable of the Sunnah, then it is preferable for him to step forward for the imamate, and his committing of sins should not prevent him from doing so. Satan may whisper to him to abandon the imamate due to his sins, in order to deter him from good. He must repent from his sins and strive against his lower self, while continuing to do good deeds like the imamate. For good deeds erase bad deeds, and the verse, "Do you enjoin righteousness upon people and forget yourselves?" (2:44), does not mean that one should abandon enjoining good just because one commits sins. Rather, it condemns those who enjoin good but do not practice it.
