Is it permissible for a person afflicted with urinary incontinence to lead the prayer (imam), and what should he do if he leads the worshippers while being excused, and is it permissible for him to read the Qur'an from the Mus-haf?

It has been previously explained that there is a difference of opinion regarding the ruling on leading prayers for someone who suffers from urinary incontinence when leading others. Your prayer is valid, and the prayer of those who prayed behind you is also valid, because they are unaware of your condition. Their prayer is valid, though disliked, according to the Malikis, and valid without dislike according to the Shafi'is. You are not required to offer expiation nor inform them. It was not obligatory for you to prevent them from praying behind you. There is no impediment to reading from the Mus'haf for someone who suffers from urinary incontinence, provided that they do not touch it without ablution.
