It was narrated from Abu Himman: That when Mu'awiyah went on Hajj, he gathered together a group of the Companions of the Messenger of Allah [SAW] at the Ka'bah and said to them: "I adjure you by Allah, did the Messenger of Allah [SAW] forbid wearing gold?" They said: "Yes." He said: "And I bear witness to that"
