It was narrated from Anas bin Malik that the Messenger of Allah said: “Whoever wears silk in this world will not wear it in the Hereafter.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا لَمْ يَلْبَسْهُ فِي الآخِرَةِ " .
