The ruling on leading prayer for one who has hemorrhoids or urinary incontinence

Question:
I am the mu'adhdhin in one of the mosques in Ta'if, and the mosque has no imam, so I lead the people in most of the obligatory prayers. I suffer from hemorrhoids, and sometimes some blood may drip or flow during the prayer. Is it permissible for me to lead the people sometimes when I am not aware of it?

Answer:
As long as the state of ritual impurity is not continuous with you, there is nothing wrong with it. If something comes out of you during the prayer and you become aware of it, you must break off the prayer and appoint someone else to complete it with them; you should delegate the leadership.
As for the one whose state of ritual impurity is constant with him—whether it is constant urination or constant passing of wind—scholars have disagreed on this:
Some of them held that he should not lead the people, because his state of ritual impurity is constant and his ritual purity is only for necessity, so he should be a ma'mum (one praying behind the imam).
And some of them permitted him to lead, because his prayer is valid in itself, since he is excused. If he prays with them, it is valid, if Allah wills. If he refrains and has someone else lead them, to avoid the disagreement, that is more cautious and better; to avoid the disagreement among scholars in that matter, if his state of ritual impurity is constant.
