It was narrated from ‘Abdullah bin ‘Umar that a man asked the Messenger of Allah صلی اللہ علیہ وآلہ وسلم “What clothes can the Muhrim wear?” The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “They should not wear shirts nor ‘Imamahs, or pants, or burnouses, or Khuffs — unless a person cannot find sandals, in which case he may wear Khuffs. But he should cut them to come lower than the ankles. And they should not wear anything that has been touched by (dyed with) saffron or Wars.” (Sahih)
