‘Abd Allaah bin Umar said A man asked the Apostle of Allaah(ﷺ) What clothing one should put on if one intend to put on ihram? He said He should not wear shirts, turbans, trousers, garments with head coverings and clothing which has any dye of waras or saffron; one should not put on shoes unless one cannot get sandals. If one cannot get sandals, one should wear the shoes, in which case one must cut them to come below the ankles.
حَدَّثَنَا مُسَدَّدٌ، وَأَحْمَدُ بْنُ حَنْبَلٍ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم مَا يَتْرُكُ الْمُحْرِمُ مِنَ الثِّيَابِ فَقَالَ " لاَ يَلْبَسُ الْقَمِيصَ وَلاَ الْبُرْنُسَ وَلاَ السَّرَاوِيلَ وَلاَ الْعِمَامَةَ وَلاَ ثَوْبًا مَسَّهُ وَرْسٌ وَلاَ زَعْفَرَانٌ وَلاَ الْخُفَّيْنِ إِلاَّ لِمَنْ لَمْ يَجِدِ النَّعْلَيْنِ فَمَنْ لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا حَتَّى يَكُونَا أَسْفَلَ مِنَ الْكَعْبَيْنِ " .
