Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللَّهِ بْنِ حُنَيْنٍ، عَنْ أَبِيهِ، عَنْ عَلِيٍّ، قَالَ نَهَانِي رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ لُبْسِ الْقَسِّيِّ وَالْمُعَصْفَرِ وَعَنْ تَخَتُّمِ الذَّهَبِ وَعَنِ الْقِرَاءَةِ فِي الرُّكُوعِ .
It was narrated that Ali said: "The Messenger of Allah (ﷺ) forbade me from wearing Al-Qassi, and clothes dyed from safflower, and from wearing gold rings, and from reciting Qura'n while bowing."
