Narated By Asma : Abdullah AbuUmar, client of Asma’, daughter of Abu Bakr, said: I saw Ibn Umar buying a Syrian garment in the market. When he saw that it had red warp, he returned it. I then came to Asma’ and mentioned it to her. She said: Bring me, slave-girl, the mantle of the Apostle of Allah (PBUH). She brought out a mantle of a course ornamented cloth, with its collar, sleeves, front, and back were hemmed with brocade.
