"Sa'sa'ah bin Suwhan came to 'Ali and said: 'Forbid to us from that which the Messenger of Allah forbade to you.' He said: 'He forbade us from Ad-Dubba', Al-Hantam, An-Naqir, Al-Ji'ah, and he forbade us from gold circles (rings), wearing silk, and wearing Al-Qassi, and red Al-Mitharah.'"
Sunan an-Nasa'i Book 48, Hadith 131
