أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، قَالَ أَنْبَأَنَا أَيُّوبُ، عَنْ عَمْرٍو، عَنْ جَابِرِ بْنِ زَيْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا لَمْ يَجِدْ إِزَارًا فَلْيَلْبَسِ السَّرَاوِيلَ وَإِذَا لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ " .
It was narrated that Ibn 'Abbas said: "I heard the Messenger of Allah say; 'If you cannot find an Izar then wear pants, and if you cannot find sandals then wear khuffs, but cut them so that they come lower than the ankles.
