It was narrated from Ibn Hunain, that 'Ali said that: The Messenger of Allah [SAW] forbade garments dyed with safflower, and from silk, and reciting Qur'an while he is bowing, and from gold rings.
أَخْبَرَنِي إِبْرَاهِيمُ بْنُ يَعْقُوبَ، قَالَ حَدَّثَنَا الْحَسَنُ بْنُ مُوسَى، قَالَ حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، أَخْبَرَنِي خَالِدُ بْنُ مَعْدَانَ، أَنَّ ابْنَ حُنَيْنٍ، حَدَّثَهُ أَنَّ عَلِيًّا قَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ ثِيَابِ الْمُعَصْفَرِ وَعَنِ الْحَرِيرِ وَأَنْ يَقْرَأَ وَهُوَ رَاكِعٌ وَعَنْ خَاتَمِ الذَّهَبِ .
