The Messenger of Allah ﷺ forbade me to wear rings of gold, to use red saddle pads, to wear garments made from a blend of linen and silk, and nabeedh made from barley. (Using translation from Aḥmad 1102)
قَالَ عَلِيٌّ «نَهَانِي النَّبِيُّ ﷺ عَنْ خَاتَمِ الذَّهَبِ وَعَنِ الْقَسِّيِّ وَعَنِ الْمِيثَرَةِ وَعَنِ الْجِعَةِ»
