It was narrated from ‘Abdullah bin 'Umar that a man the Messenger of Allah P.B.U.H what clothes may the Muhrim wear? The Messenger of Allah P.B.U.H said: "He should not wear a shirt, or turbans (or head cover), pants or pajamas, hooded cloaks and no leather socks, unless he cannot find sandals, in which case he may wear the leather socks but should cut them to below the ankles. And he should not wear any clothes that have been touched (dyed) with saffron or Wars.(Sahih)
