Sahih Muslim , Book 7, Hadith 2648 (USC-MSA) ⓘ

Salim reported on the authority of his father ('Abdullah b. 'Umar) that the Messenger of Allah was asked what a Muhrim should wear, whereupon he said: A Muhrim should not wear a shirt, or a turban, or a cap, or trousers, or a cloth touched with wars or with saffron, nor (should he wear) stockings, but in case he does not find shoes, but (before wearing stockings) be should trim them (in such a way) that these should become lower than the ankles.

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَعَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، كُلُّهُمْ عَنِ ابْنِ عُيَيْنَةَ، - قَالَ يَحْيَى أَخْبَرَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، - عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، - رضى الله عنه - قَالَ سُئِلَ النَّبِيُّ صلى الله عليه وسلم مَا يَلْبَسُ الْمُحْرِمُ قَالَ ‏ "‏ لاَ يَلْبَسُ الْمُحْرِمُ الْقَمِيصَ وَلاَ الْعِمَامَةَ وَلاَ الْبُرْنُسَ وَلاَ السَّرَاوِيلَ وَلاَ ثَوْبًا مَسَّهُ وَرْسٌ وَلاَ زَعْفَرَانٌ وَلاَ الْخُفَّيْنِ إِلاَّ أَنْ لاَ يَجِدَ نَعْلَيْنِ فَلْيَقْطَعْهُمَا حَتَّى يَكُونَا أَسْفَلَ مِنَ الْكَعْبَيْنِ ‏" ‏ ‏.‏
