Sunan an-Nasa'i 2674

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَجُلاً، سَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم مَا يَلْبَسُ الْمُحْرِمُ مِنَ الثِّيَابِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ تَلْبَسُوا الْقَمِيصَ وَلاَ الْعَمَائِمَ وَلاَ السَّرَاوِيلاَتِ وَلاَ الْبَرَانِسَ وَلاَ الْخِفَافَ إِلاَّ أَحَدٌ لاَ يَجِدُ نَعْلَيْنِ فَلْيَلْبَسْ خُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ وَلاَ تَلْبَسُوا شَيْئًا مَسَّهُ الزَّعْفَرَانُ وَلاَ الْوَرْسُ ‏"‏ ‏.‏

It was narrated from 'Abdullah bin 'Umar that:a man asked the Messenger of Allah what clothes the Muhrim should wear? The Messenger of Allah said: "Do not wear shirts, or 'Imamahs, or pants, or burnouses, or Khuffs except if someone does not have sandals, in which case let him wear Khuffs, and cut them so that they come below the ankles. And do not wear any garment that has been touched by (dyed with) saffron or Wars
