If the imam’s ablution is broken, does the prayer of the ma’mum (those praying behind him) become invalid?

Question:
May Allah grant you success. If the imam’s ablution is broken, does he appoint a replacement, or does his prayer and the prayer of the ma’mum become invalid?

Answer:
As for appointing a replacement before his ablution is broken, if he senses that his ablution is about to be broken, then appointing a replacement is valid without any scholarly disagreement. However, if his ablution is broken before he appoints a replacement, this is a matter of disagreement among scholars. It is safer, without a doubt, and more exonerating for the conscience, for the replacement to start the prayer from the beginning. Yes.
