Narrated Thawban: The Messenger of Allah صلی اللہ علیہ وسلم said: Three things one is not allowed to do: supplicating Allah specifically for himself and ignoring others while leading people in prayer; if he did so, he deceived them; looking inside a house before taking permission: if he did so, it is as if he entered the house, saying prayer while one is feeling the call of nature until one eases oneself.

Narrated Abd Allaah bin Muhammad: We were in the company of Aishah. When her food was brought in, al-Qasim stood up to say his prayer. Thereupon, Aishah said: I heard the Messenger of Allaah صلی اللہ علیہ وسلم say: Prayer should not be offered in presence of meals, nor at the moment when one is struggling with two evils (e. g. when one is feeling the call of nature.)

Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم said: It is not permissible for a man who believes in Allah and in the Last Day that he should say the prayer while he is feeling the call of nature until he becomes light (by relieving himself). Then the narrator Thawr bin Yazid transmitted a similar tradition with the following wordings: "It is not permissible for a man who believes in Allah and in the Last Day that he should lead the people in prayer but with their permission; and that he should not supplicate to Allah exclusively for himself leaving all others. If he did so, he violated trust. " Abu Dawud said: This is a tradition reported by the narrators of Syria; no other person has joined them in relating this tradition.
