It was narrated from `Imran bin Hittan, according to what Harb thinks, who asked Ibn `Abbas about silk garments. He said:

Ask `A`ishah about that. So he asked `A`ishah and she said: Ask Ibn `Umar (...). So he asked Ibn `Umar, and he said: Abu Hafs told me that the Messenger of Allah (ﷺ) said: `Whoever wears silk in this world will have no share of it in the Hereafter.”

حَدَّثَنَا عَبْدُ الصَّمَدِ، حَدَّثَنَا حَرْبٌ، حَدَّثَنَا يَحْيَى، عَنْ عِمْرَانَ بْنِ حِطَّانَ، فِيمَا يَحْسِبُ حَرْبٌ أَنَّهُ سَأَلَ ابْنَ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ عَنْ لَبُوسِ الْحَرِيرِ، فَقَالَ سَلْ عَنْهُ عَائِشَةَ فَسَأَلَ عَائِشَةَ فَقَالَتْ سَلْ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَسَأَلَ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَقَالَ حَدَّثَنِي أَبُو حَفْصٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا فَلَا خَلَاقَ لَهُ فِي الْآخِرَةِ‏.‏
