Muwatta Malik #743
Hajj
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَلْبَسَ الْمُحْرِمُ ثَوْبًا مَصْبُوغًا بِزَعْفَرَانٍ أَوْ وَرْسٍ وَقَالَ
" مَنْ لَمْ يَجِدْ نَعْلَيْنِ فَلْيَلْبَسْ خُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ " .
Yahya related to me from Malik from 'Abdullah ibn Dinar that
Abdullah ibn Umar said, "The Messenger of Allah, may Allah bless him
and grant him peace, forbade anyone in ihram to wear a garment which
had been dyed with saffron or yellow dye, and said, 'Anyone that
cannot find sandals can wear leather socks, but he should cut them off
below the ankles.' "
