It was narrated that Al-Bara bin 'Azib said:
The Messenger of Allah commanded us to do seven things, and forbade us form seven things. He commanded us to visit the risk, to reply (say: Yarhamuk Allah, may Allah have mercy on you) to one who sneezes, to fulfill our oaths, to support the oppressed, to spread the greeting of Salam, to accept invitation, and to attend funerals. And he forbade us from using gold rings, silver vessels, Mayathir, the Qasiyyah, Al-Istabraq, silk and Ad-Dibaj.
