Is it permissible for one who is in a voluntary prayer or in the bathroom to repeat the adhan when he hears it?

Question:
He says: Honorable Shaykh, may Allah grant you success. If a person is performing a voluntary prayer, should he repeat the adhan with the mu'adhdhin? And likewise, if he is in the place of relieving himself, should he repeat it with him?

Answer:
He should not repeat it with him in either case. In prayer, nothing that is not prescribed in it is to be introduced into it. As for the bathroom, the remembrance of Allah is not disliked in it; rather, it is the remembrance of Allah in the bathroom that is disliked, or rather, ordinary conversation. It is disliked to speak and say, "So-and-so, bring such-and-such," or to chat with people. It is disliked, and Allah detests this, so one should not talk inside the bathroom. Yes. They said: except out of necessity, such as warning someone who is unaware of a deadly danger, or a blind man who is about to fall into a well or fire. In that case, you alert him, even if you are in the middle of relieving yourself, because of the necessity.
