عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِذَا لَمْ يَجِدِ الْمُحْرِمُ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ))
Narrated by Sayyiduna Abdullah bin Umar (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him) said: When a person in Ihram does not find shoes, he should wear socks, but he should cut them below the ankles.
