It was narrated from 'Abdullah bin 'Umar that:a man asked the Messenger of Allah what clothes the Muhrim should wear? The Messenger of Allah said: "Do not wear shirts, or 'Imamahs, or pants, or burnouses, or Khuffs except if someone does not have sandals, in which case let him wear Khuffs, and cut them so that they come below the ankles. And do not wear any garment that has been touched by (dyed with) saffron or Wars
