"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. (Using translation from Nasāʾī 2679)

خَطَبَ رَسُولُ اللهِ ﷺ وَقَالَ إِذَا لَمْ يَجِدِ الْمُحْرِمُ إِزَارًا فَلْيَلْبَسِ السَّرَاوِيلَ وَإِذَا لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ
