Hadith
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم. وَعَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّ رَجُلاً سَأَلَهُ مَا يَلْبَسُ الْمُحْرِمُ فَقَالَ " لاَ يَلْبَسِ الْقَمِيصَ وَلاَ الْعِمَامَةَ وَلاَ السَّرَاوِيلَ وَلاَ الْبُرْنُسَ وَلاَ ثَوْبًا مَسَّهُ الْوَرْسُ أَوِ الزَّعْفَرَانُ، فَإِنْ لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا حَتَّى يَكُونَا تَحْتَ الْكَعْبَيْنِ ".
Narrated Ibn `Umar:A man asked the Prophet (ﷺ) : "What (kinds of clothes) should a Muhrim (a Muslim intending to perform `Umra or Hajj) wear? He replied, "He should not wear a shirt, a turban, trousers, a head cloak or garment scented with saffron or Wars (kinds of perfumes). And if he has no slippers, then he can use Khuffs (socks made from thick fabric or leather) but the socks should be cut short so as to make the ankles bare." (See Hadith No. 615, Vol)
