I visited al-Bara' b. 'Azib and heard him say: Allah's Messenger (ﷺ) commanded us to do seven things and forbade us to do seven (things). He commanded us to visit the sick, to follow the funeral procession, to answer the sneezer, to fulfil the vow, to help the poor, to accept the invitation and to greet everybody, and he forbade us to wear rings or gold rings, to drink in silver (vessels), and to use the saddle cloth made of red silk, and to wear garments made of Qassi material, or garments made of silk or brocade and velvet.
The Book of Clothes and Adornment
Sahih Muslim 2066 a - Commentary by Imam al-Nawawi
Commanded Matters
The Prophet (ﷺ) commanded seven acts of social responsibility: visiting the sick demonstrates compassion; following funeral processions honors the deceased; responding to sneezers with "Yarhamukallah" acknowledges Allah's mercy; fulfilling vows maintains trustworthiness; helping the poor fulfills communal obligations; accepting invitations fosters brotherhood; and universal greeting spreads peace.
Prohibited Adornments
The prohibition against gold rings and silver vessels for men prevents extravagance and imitation of feminine adornment. Silk garments are forbidden as they symbolize softness contrary to masculine dignity. Red silk saddle cloths and brocade/velvet fabrics are prohibited due to their association with pride and worldly attachment.
Qassi Material
Qassi refers to fabric mixing silk with cotton or wool. Scholars differ whether its prohibition is absolute or applies only when silk predominates. The wisdom lies in preventing gradual deviation from pure prohibitions and maintaining distinction from non-Muslim practices.
Legal Wisdom
These prohibitions cultivate modesty, prevent class distinctions, and direct wealth toward beneficial uses. Exceptions exist for medical necessity or combat. Women are permitted these adornments within marital contexts, reflecting Islamic balance between prohibition and necessity.
