239. Abu 'Umara al-Bara' ibn 'Azib said, "The Prophet, may Allah bless him and grant him peace, instructed us to do seven things and forbade us seven. He instructed us to visit the sick, to join funeral processions, to bless people who sneeze, to fulfil our oaths, to help the wronged, to accept invitations, and to return the greeting. He forbade us gold rings, drinking from silver vessels, red silk, fine silk, mixed silk and cotton, and wearing silk and istibraq silk, and brocade." [Agreed upon]
