Musnad Abu Ya'la al-Mawsili 3:341

Abu Khaythama narrated to us, Ismail bin Ibrahim narrated to us, from Ayyub, from Nafi’, from Ibrahim bin Hunayn, from his grandfather Hunayn, from Ali, who said: The Messenger of Allah (may Allah bless him and grant him peace) forbade me from wearing saffron-dyed garments, from *al-Qassi* (silk-blend garments), from gold rings, and from reciting [the Quran] while bowing. Ayyub said: Or he said, "or that I recite while I am bowing." Abu Khaythama said: Ismail retracted his statement "from his grandfather" and said afterwards: "from Ibrahim bin [so-and-so] bin Hunayn, from his father."
