Allah's Messenger (ﷺ) ordered us to do seven (things): to visit the sick, to
follow the funeral processions, to say Tashmit to a sneezer, to help
the weak, to help the oppressed ones, to propagate As-Salam
(greeting), and to help others to fulfill their oaths (if it is not
sinful). He forbade us to drink from silver utensils, to wear gold
rings, to ride on silken saddles, to wear silk clothes, Dibaj (thick
silk cloth), Qassiy and Istabraq (two kinds of silk). (See
