حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَجُلاً، قَالَ يَا رَسُولَ اللَّهِ مَا يَلْبَسُ الْمُحْرِمُ مِنَ الثِّيَابِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ يَلْبَسُ الْمُحْرِمُ الْقَمِيصَ، وَلاَ السَّرَاوِيلَ، وَلاَ الْبُرْنُسَ، وَلاَ الْخُفَّيْنِ، إِلاَّ أَنْ لاَ يَجِدَ النَّعْلَيْنِ، فَلْيَلْبَسْ مَا هُوَ أَسْفَلُ مِنَ الْكَعْبَيْنِ ".
