Sahih Muslim | Book 24 | Hadith Number 5226

Narrated by Ali
Ali reported: He the Holy Prophet (may peace be upon him), forbade me that I should wear my ring in this (forefinger) or in that near it. 'Asim (one of the narrators in the chain of transmitters) said: He did not remember which of the two (fingers) he pointed out; and he forbade to wear Qassi material (silk garments), and to sit on the silk saddle cloth, and he said: As regards Qassi, it is a variegated garment which was brought from Egypt and Syria which had figures upon it, and as regards Mayathir, it is something which women prepared for their husbands as red cloths for their saddles.
