"O Messenger of Allah, what clothes should we wear when we enter Ihram?" He said: "Do not wear a shirt (or shirts), or 'Imamahs, or pants, or Khuffs unless someone Cannot find sandals, in which case he should cut them (the Khuffs) so that they come beneath the ankles or any garment that has been touched by (dyed with ) wars or saffron.  

يَا رَسُولَ اللَّهِ مَا نَلْبَسُ مِنَ الثِّيَابِ إِذَا أَحْرَمْنَا قَالَ لاَ تَلْبَسُوا الْقَمِيصَ وَقَالَ عَمْرٌو مَرَّةً أُخْرَى الْقُمُصَ وَلاَ الْعَمَائِمَ وَلاَ السَّرَاوِيلاَتِ وَلاَ الْخُفَّيْنِ إِلاَّ أَنْ لاَ يَكُونَ لأَحَدِكُمْ نَعْلاَنِ فَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ وَلاَ ثَوْبًا مَسَّهُ وَرْسٌ وَلاَ زَعْفَرَانٌ
