Yahya - bin Ishaq - said: "Salim said: 'What is Al-Istabraq?' I said: 'A thick type of Ad-Dibaj, and a coarse type of it.' He said: 'I heard 'Abdullah (bin 'Umar) say: "Umar saw a Hullah of Sundus with a man, and he brought it to the Messenger of Allah [SAW] and said: 'Buy this'" and he quoted the Hadith.

أَخْبَرَنَا عِمْرَانُ بْنُ مُوسَى، قَالَ حَدَّثَنَا عَبْدُ الْوَارِثِ، قَالَ حَدَّثَنَا يَحْيَى، - وَهُوَ ابْنُ أَبِي إِسْحَاقَ - قَالَ قَالَ سَالِمٌ مَا الإِسْتَبْرَقُ قُلْتُ مَا غَلُظَ مِنَ الدِّيبَاجِ وَخَشُنَ مِنْهُ ‏.‏ قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ يَقُولُ رَأَى عُمَرُ مَعَ رَجُلٍ حُلَّةَ سُنْدُسٍ فَأَتَى بِهَا النَّبِيَّ صلى الله عليه وسلم فَقَالَ ‏ "‏ اشْتَرِ هَذِهِ ‏"‏ ‏.‏ وَسَاقَ الْحَدِيثَ ‏.‏
