Amir bin Ubaydah al-Bahili, the judge of Basrah, said: I set out with a group from Bahilah until we came to Sayyiduna Anas bin Malik (may Allah be pleased with him). He mentioned the hadith. We said: "Tell us about silk (khazz)." He brought out a silk cloak (jubbah) and said: "This I wear, but I do not like it. The Companions of the Prophet (peace and blessings be upon him) (may Allah be pleased with them) used to wear it, except Sayyiduna Umar (may Allah be pleased with him) and Sayyiduna Ibn Umar (may Allah be pleased with them both)."
