The Lawfulness of Wearing Silk if One is Suffering from an Itch
عَنْ أَنَسٍ رضى اللَّه عَنْهُ قَالَ: رَخَّصَ رَسُولُ اللَّهِ ، صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، لِلزُّبَيْرِ وَعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ رضى اللَّه عَنْهُمَا فِي لُبْسِ الْحَرِيرِ لِحِكَّةٍ بِهِمَا.((مُتَّفَقٌ عَلَيْهِ))
Anas (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) permitted Zubair and `Abdur-Rahman bin `Auf (May Allah be pleased with them) to wear silk because they were suffering from an itch. [Al-Bukhari and Muslim].
