Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he said: "A person remains in prayer as long as he stays at his prayer place, and waiting for the prayer keeps him seated there. The angels who are with him say: O Allah! Forgive him, O Allah! Have mercy on him, and this continues as long as he remains in a state of ablution."
