I used to write down everything I heard from the Messenger of Allah (may Allah's peace and blessings be upon him) in order to memorize it. The Quraysh prohibited me, saying: "Do you write down everything that you hear from the Messenger of Allah (may Allah's peace and blessings be upon him) while the Messenger of Allah (may Allah's peace and blessings be upon him) is a human being who speaks in anger and pleasure?" So, I stopped writing and mentioned that to the Messenger of Allah (may Allah's peace and blessings be upon him). Thereupon, he pointed his finger to his mouth and said: "Write down; for by the One in Whose Hand my soul is, nothing comes out of it except the truth."

I set out with the delegation of Banu ‘Āmir to meet the Messenger of Allah (may Allah's peace and blessings be upon him). We said: You are our master. He said: "The Master is Allah." We said: And the best of us in superiority and the greatest among us in bounty. He said: "Say what you have to say, or part of what you have to say, but do not let the devil deviate you (in praising me)."
