Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "When any one of you waits for prayer while sitting on his prayer place, he is considered to be in prayer, and the angels say: O Allah! Forgive him, have mercy on him, (this continues) until he gets up and leaves or commits a bad hadath." It was asked: What is a bad hadath? He said: "That he passes wind audibly or silently."
