Yahya bin Hamza bin Waqd يحيى بن حمزة بن واقد · The Book of Adornment

The Messenger of Allah forbade wearing silk and gold, unless it was broken (into smaller pieces).

"The Prophet forbade me from Al-Qassi, silk, gold rings, and that I recite Qur'an while bowing." Hisham contradicted him, he did not narrate it in Marfu' form.
