Hudhayfah bin Yaman (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) held the flesh of his or my shin and said: "This is the place for the izar (lower garment). If you are not satisfied with this, then let it down a little more. Then if you want to lower it further, the izar cannot be lowered below the ankles." __QUR_N__ Imam Tirmidhi says: This hadith is hasan sahih. Both Sufyan al-Thawri and Shu’bah have also narrated it from Abu Ishaq al-Sabi’i.
