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 (صلی اللہ علیہ وسلم) and said: Buy this" and he quoted the Hadith.
