Abu Hakimah Al-Abdi, may Allah have mercy on him, said: Sayyiduna Ali, may Allah be pleased with him, came to me while I was writing a Mushaf, so he began to watch me write and said: "Make your pen beautiful." So I sharpened my pen, then began to write, and he looked again and said: "Yes!" Then he said: "Clarify it as Allah has clarified."
