Narrated Ibn `Abbas:
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عَمْرِو بْنِ دِينَارٍ ، عَنْ جَابِرِ بْنِ زَيْدٍ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " مَنْ لَمْ يَكُنْ لَهُ إِزَارٌ فَلْيَلْبَسِ السَّرَاوِيلَ، وَمَنْ لَمْ يَكُنْ لَهُ نَعْلاَنِ فَلْيَلْبَسْ خُفَّيْنِ " .
The Prophet (ﷺ) said, "Whoever has no Izar (waist sheet), can wear trousers; and whoever has no sandals, can wear Khuffs (socks made from thick fabric or leather, but cut them short below the ankles)."
