Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says: I came to the Noble Prophet (peace and blessings be upon him), I was wearing an izar (lower garment), and it was moving. The Prophet (peace and blessings be upon him) asked: "Who is this?" I said: I am Abdullah bin Umar. The Prophet (peace and blessings be upon him) said: "If you are truly a servant of Allah, then raise your izar." So I raised my izar up to half of my shins. After that, his lower garment remained like that until he passed away.
