Musannaf Ibn Abi Shayba 16:714

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from Ibn Abi Najih, from Mujahid, who said: I came to ‘Abd al-Rahman ibn Abi Layla, and I had gold dust with me. He said, "Do you intend to adorn a Mushaf (copy of the Quran) with it?" I said, "No." He said, "To adorn a sword with it?" I said, "I will adorn my daughter with it." He said, "Are you likely to make them into bells? For that is disliked."
