He heard the Messenger of Allah say: "If the Muhrim cannot find an Izar, then let him wear pants, and if he cannot find sandals, them let him wear Khuff."
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْمُحْرِمُ إِذَا لَمْ يَجِدِ الإِزَارَ فَلْيَلْبَسِ السَّرَاوِيلَ وَإِذَا لَمْ يَجِدِ النَّعْلَيْنِ فَلْيَلْبَسِ الْخُفَّيْنِ
