'What should we wear when we enter Ihram?' He said: 'Do not wear a shirt, or an 'Imamah, or pants, or a burnouts, or Khuffs unless you cannot find any sandals. If you cannot find any sandals, then wear something that comes beneath the ankles. (Using translation from Nasāʾī 2676)  

نَادَى النَّبِيَّ ﷺ رَجُلٌ فَقَالَ مَا نَلْبَسُ إِذَا أَحْرَمْنَا؟ فَقَالَ «لَا تَلْبَسِ الْقَمِيصَ وَلَا الْعِمَامَةَ وَلَا السَّرَاوِيلَ وَلَا الْبُرْنُسَ وَلَا الْخُفَّيْنِ إِلَّا أَنْ لَا تَجِدَ نَعْلَيْنِ فَإِنْ لَمْ تَجِدِ النَّعْلَيْنِ فَمَا دُونَ الْكَعْبَيْنِ»  

"A man came to the Prophet and said: 'What should we wear when we enter Ihram?' He said: 'Do not wear shirts, or 'Imamahs, or burnouses, or pants, or Khuffs unless there are no sandals; if there are no sandals, then wear Khuffs that come beneath the ankles. And (do not wear) any garment that has been dyed with Wars or saffron, or has been touched by Wars or saffron. (Using translation from Nasāʾī 2677)  

نَادَى النَّبِيَّ ﷺ رَجُلٌ فَقَالَ مَا نَلْبَسُ إِذَا أَحْرَمْنَا؟ قَالَ لَا تَلْبَسُوا الْقُمُصَ وَلَا السَّرَاوِيلَاتِ وَلَا الْخِفَافَ إِلَّا أَنْ لَا يَكُونَ نِعَالًا فَإِنْ لَمْ يَكُنْ نِعَالٌ فَخُفَّيْنِ دُونَ الْكَعْبَيْنِ وَلَا ثَوْبًا مَصْبُوغًا بِوَرْسٍ أَوْ زَعْفَرَانٍ أَوْ مَسَّهُ وَرْسٌ أَوْ زَعْفَرَانٌ
