باب الصَّلاَةِ فِي الْقَمِيصِ وَالسَّرَاوِيلِ وَالتُّبَّانِ وَالْقَبَاءِ
Sahih al-Bukhari 366

Narrated Ibn `Umar:

A person asked Allah's Messenger (ﷺ), "What should a Muhrim wear?" He replied, "He should not wear shirts, trousers, a burnus (a hooded cloak), or clothes which are stained with saffron or Wars (a kind of perfume). Whoever does not find a sandal to wear can wear Khuffs (socks made from thick fabric or leather), but these should be cut short so as not to cover the ankles.

حَدَّثَنَا عَاصِمُ بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، قَالَ سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ مَا يَلْبَسُ الْمُحْرِمُ فَقَالَ ‏ "‏ لاَ يَلْبَسُ الْقَمِيصَ وَلاَ السَّرَاوِيلَ وَلاَ الْبُرْنُسَ وَلاَ ثَوْبًا مَسَّهُ الزَّعْفَرَانُ وَلاَ وَرْسٌ، فَمَنْ لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا حَتَّى يَكُونَا أَسْفَلَ مِنَ الْكَعْبَيْنِ ‏"‏‏.‏ وَعَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ‏.‏
