It was narrated that 'Ali said:
My beloved, the Messenger of Allah [SAW], forbade me three things but I do not say that he forbade them to the people. He forbade me from wearing rings of gold, from wearing Al-Qassi, and Al-Mu'asfar Al-Mufaddam (garments that are deeply dyed with safflower), and (he forbade me) from reciting Qur'an when prostrating or bowing. He was followed (in that narration) by Ad-Dahhak bin 'Uthman.
