Sayyiduna Ibn Umar (may Allah be pleased with them both) says: I went in to the Prophet (peace and blessings be upon him) while my lower garment was rustling, so he (peace and blessings be upon him) asked: "Who is this?" I said: Abdullah. He (peace and blessings be upon him) said: "If you are Abdullah (a servant of Allah), then raise your lower garment." So I raised my lower garment to the middle of the shins, and he (Ibn Umar, may Allah be pleased with them both) kept wearing his lower garment that way until his death.
