‘Asim ibn Kulayb narrated that Abu Burdah narrated from him that he asked ‘Ali (may Allah be pleased with him) «قسي» What is it? He replied that it was a cloth which used to come to us (in Hijaz) from Syria or Egypt, and it had broad silk stripes on it and designs like citron were made on it, and «ميثرة» “Zeen posh”was the cloth which women used to make of silk for their husbands. It was like a fringed sheet, and they used to dye it with yellow color, like the scarves used for covering. And Jarir narrated that Zayd narrated from him that «قسية» they were checkered clothes which were imported from Egypt and contained silk mixed in them, and «ميثرة» saddlecloths made from the skins of wild animals. Abu ‘Abdullah Imam Bukhari (may Allah have mercy on him) said that «ميثرة» in the explanation of it, the narration of ‘Asim is superior in terms of the number of chains and authenticity.

Narrated Ibn Azib: The Prophet forbade us to use the red Mayathir and to use Al-Qassiy.
