‘Ali said God's messenger forbade wearing Qassi material and anything dyed with saffron, using a gold ring, and reciting the Qur'an when making the bow. Muslim transmitted it.

وَعَنْ عَلِيٍّ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ لُبْسِ الْقَسِّيِّ وَالْمُعَصْفَرِ وَعَنْ تَخْتُّمِ الذَّهَبِ وَعَنْ قِرَاءَةِ الْقُرْآنِ فِي الرُّكُوعِ. رَوَاهُ مُسلم
