Musannaf Ibn Abi Shayba 22:335

'Abdah narrated to us, from al-Zibriqan, who said: I said to Abu Razin, "I have a Mushaf (copy of the Quran) that I want to decorate with gold, and I want to write at the beginning of each Surah such-and-such verse." Abu Razin said: "Do not add anything to it from the affairs of the world, whether little or much."
