قَالَ قَرَأْتُ عَلَى عَبْدِ الرَّحْمَنِ : مَالِكٌ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ قَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَلْبَسَ الْمُحْرِمُ ثَوْبًا مَصْبُوغًا بِزَعْفَرَانٍ أَوْ وَرْسٍ وَقَالَ مَنْ لَمْ يَجِدْ نَعْلَيْنِ فَلْيَلْبَسْ خُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنْ الْكَعْبَيْنِ
مسند امام احمد بن حنبل · Hadith 5336
It was narrated that Abdullah ibn 'Umar said: The Messenger of Allah (PBUH) forbade muhrim (pilgrim in lhram) to wear any garment that has been dyed with saffron or wars (memecylon tinctorium, a plant dye), and he said: Whoever cannot find sandals, let him wear Khuffayn and cut them so that they come lower than the ankles.
