Al-Bara' ibn 'Azib said, "The Messenger of Allah, 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 return the greeting, and to accept invitations. He forbade us gold rings, silver vessels, red (silk) saddle clothes, Qassi (silk and flax) garments, thick brocade, embroidered silk, and pure silk."
