Abu Shaykh al-Huna'i (may Allah have mercy on him) narrates that one day, while the Companions of the Messenger of Allah (peace and blessings be upon him) were with him, Mu'awiyah (may Allah be pleased with him) said: Do you know that the Messenger of Allah (peace and blessings be upon him) forbade wearing gold except when it is in small pieces? They said: By Allah, yes. He said: Do you know that the Messenger of Allah (peace and blessings be upon him) forbade riding on leopard skins? They said: By Allah, yes. He said: Do you know that the Messenger of Allah (peace and blessings be upon him) forbade combining Hajj and Umrah? They said: By Allah, no.
