It is narrated from Hazrat Thawban (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: It is not permissible for a Muslim man to even look into someone’s house without permission; if he does so, it is as if he has entered. And a person who leads people in prayer should not make supplication only for himself, leaving out the followers, because if he does so, he is being dishonest with them. And no person should perform prayer while suppressing the urge to urinate or defecate; rather, he should first relieve himself.
