It is narrated from Hazrat Anas (may Allah be pleased with him) that his grandmother, Hazrat Maleeka, once invited the Prophet (peace and blessings be upon him) for a meal. After the Prophet (peace and blessings be upon him) had eaten, he said, "Get up, I will pray for you." Hazrat Anas (may Allah be pleased with him) says that he got up and brought a mat which had turned black due to long use. He sprinkled water on it. The Prophet (peace and blessings be upon him) stood on it, and he (Anas) and an orphan boy stood behind the Prophet (peace and blessings be upon him), and the elderly lady stood behind them. Then the Prophet (peace and blessings be upon him) led us in two rak'ahs of prayer and then departed.
