[Machine] The Messenger of Allah ﷺ said, "Whoever wears silk in this world, he will not wear it in the Hereafter." Abdullah ibn Zubayr said, "By his own soul, whoever does not wear it in the Hereafter will not enter Paradise, because Allah Almighty said, 'And their clothing therein will be silk.'" (Surah Al-Hajj, 22:23) In another narration, Ali also said the same, and Ibn Zubayr mentioned that it is because of Allah Almighty's statement, "And their clothing therein will be silk." (Surah Al-Hajj, 22:23)  

قَالَ رَسُولُ اللهِ ﷺ مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا لَا يَلْبَسُهُ فِي الْآخِرَةِ قَالَ عَبْدُ اللهِ بْنُ الزُّبَيْرِ مِنْ قِبَلِ نَفْسِهِ وَمَنْ لَمْ يَلْبَسْهُ فِي الْآخِرَةِ لَمْ يَدْخُلِ الْجَنَّةَ؛ لِأَنَّ اللهَ تَعَالَى قَالَ {وَلِبَاسُهُمْ فِيهَا حَرِيرٌ} [الحج 23] وَفِي رِوَايَةِ عَلِيٍّ وَقَالَ ابْنُ الزُّبَيْرِ وَذَلِكَ لِقَوْلِ اللهِ تَعَالَى {وَلِبَاسُهُمْ فِيهَا حَرِيرٌ} [الحج 23]
