Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: His maternal grandmother, Sayyidah Maleekah (may Allah be pleased with her), invited the Prophet Muhammad (peace and blessings be upon him) for a meal that she had prepared for him. The Prophet (peace and blessings be upon him) ate it, then he said: "Stand up so that I may lead you in prayer." Sayyiduna Anas (may Allah be pleased with him) says: I got up and went to the mat, which had turned black due to excessive use. I washed it with water. The Prophet (peace and blessings be upon him) stood on it, and I and another boy formed a row behind him, and the elderly woman stood behind us. The Prophet (peace and blessings be upon him) led us in two rak‘ahs of prayer and then concluded the prayer.
