وَعَن أنسٍ قَالَ: رَخَّصَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِلزُّبَيْرِ وَعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ فِي لبس الْحَرِير لحكة بهما وَفِي رِوَايَة لمُسلم قَالَ: إنَّهُمَا شكوا من الْقمل فَرخص لَهما فِي قمص الْحَرِير

Anas told that God’s messenger gave licence to az-Zubair and ‘Abd ar-Rahman b. ‘Auf to wear silk because of an itch which they had. (Bukhari and Muslim.) In a version by Muslim he said they complained of bugs and he gave them licence to wear silk shirts.
