It was narrated from Ibn 'Umar that:a man asked the Messenger of Allah what garments we should wear when we enter Ihram. He said: "Do not wear shirts, or pants, or 'Imamahs, or burnouses, or Khuffs unless someone does not have any sandals, in which case he should wear Khuffs that come beneath the ankles. And do not wear any garment that has been touched by (dyed with) Wars or saffron
