Musannaf Ibn Abi Shaybah 8783 — Those who disliked writing the Quran

Abu Hakimah al-Abdi said: We used to write mushafs in Kufah. Once, while we were writing, Sayyiduna Ali (may Allah be pleased with him) passed by us and said: Keep the nib of your pen broad. So I cut my pen to make it broad and then wrote. He said: In this way, give light to what Allah has given light.
