Sayyiduna Abu Umamah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Whoever bears witness that I am the Messenger of Allah should not attend the prayer while holding back urine or stool, until he has relieved himself. And whoever bears witness that I am the Messenger of Allah and then leads a people in prayer should not, when supplicating, make supplication specifically for himself alone (rather, he should supplicate for all). And whoever bears witness that I am the Messenger of Allah should not enter a house until he has sought permission and first given salam. If he sends his gaze into the inner part of the house, it is as though he has entered."
