Muawiyah bin Suwaid bin Muqrin reports: I was present in the company of Sayyiduna Bara’ bin Azib (may Allah be pleased with him), and I heard him narrate: The Prophet (peace and blessings be upon him) forbade us from seven things: gold rings, Mayathir, Qassi (a specific type of silk cloth to sit on), Dibaj, Harir, and Istabraq (specific types of silk garments), and from drinking from silver vessels.
