Sayyiduna Anas bin Malik (may Allah be pleased with him) says that one of my uncles prepared food for the Noble Prophet (peace and blessings be upon him) and came to him saying, "O Messenger of Allah! I wish that you eat food at my house." So the Prophet (peace and blessings be upon him) went to him. In the house, there was a mat made of date-palm leaves lying there. The Prophet (peace and blessings be upon him) ordered regarding one side of it, so it was cleaned and water was sprinkled on it. Then the Prophet (peace and blessings be upon him) prayed on it, and we also performed prayer with him.
