Musannaf Ibn Abi Shaybah 32229 — Those who said: honor the Quran

Ubaydullah bin Sulayman al-Abdi said that Abu Hakimah al-Abdi said: We used to write the Qur'an in mushafs in Kufah. Sayyiduna Ali (may Allah be pleased with him) passed by us while we were writing. He stopped and said: "Cut the nib of your pen." He said: So I cut its nib and then wrote, and he said: "Make it clear in this way, just as Allah has made it clear."
