وَعَنْ شَدَّادِ بْنِ أَوْسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «خَالِفُوا الْيَهُودَ فَإِنَّهُمْ لَا يُصَلُّونَ فِي نِعَالِهِمْ وَلَا خِفَافِهِمْ» . رَوَاهُ أَبُو دَاوُد
Shaddad b. Aus reported God’s Messenger as saying, “Act differently from the Jews, for they do not pray in their sandals or their shoes.”* * Khuff (pl. khifaf), an article of footwear which came up above the ankle. Traditions tell that the Prophet allowed pilgrims to wear the khuff only when unable to procure sandals, but said they must be cut to come below the ankle. Cf. Bukhari, Hajj, 21, 23; Libas, 8, 4, 15, 73. Abu Dawud transmitted it.
