Muslim bin Abi Bakrah (may Allah have mercy on him) narrates from his father (may Allah be pleased with him): I went out with the Prophet (peace and blessings be upon him) for the Subh prayer, and whenever he (peace and blessings be upon him) passed by a man, he would call him to the prayer or nudge him with his foot.
