The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2647
Ibn 'Umar (Allah be pleased with them) reported that a person asked the Messenger of Allah (may peace be upon him) what a Muhrim should put on as dress. Thereupon the Messenger of Allah (may peace be upon him) said: Do not put on a shirt or a turban, or trousers or a cap, or leather stockings except one who does not find shoes; he may put on stockings but he should trim them below the ankles. And do not wear clothes to which saffron or wars is applied.
