Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) said: I used to write down whatever I heard from the Messenger of Allah (peace and blessings be upon him) with the intention of memorizing it. Then the Quraysh forbade me and said: You write down whatever you hear from the Messenger of Allah (peace and blessings be upon him), even though the Messenger of Allah (peace and blessings be upon him) is also a human being and speaks in states of anger and pleasure. So I stopped writing and mentioned this to the Messenger of Allah (peace and blessings be upon him). He pointed towards his blessed mouth with his finger and said: "Write! By Him in whose hand is my soul, nothing comes out of it except the truth and righteousness."
Narrated Abdullah ibn Amr ibn al-As: I used to write everything which I heard from the Messenger of Allah ﷺ. I intended (by it) to memorise it. The Quraysh prohibited me saying: Do you write everything that you hear from him while the Messenger of Allah ﷺ is a human being: he speaks in anger and pleasure? So I stopped writing, and mentioned it to the Messenger of Allah ﷺ. He signalled with his finger to him mouth and said: Write, by Him in Whose hand my soul lies, only right comes out from it.
Shaykh Umar Farooq Saeedi
Benefits and Issues: Benefit: A messenger is a messenger and a proof (hujjah) in every circumstance. Their entire life, in every situation, is an example for the Ummah to follow. And then Muhammad, the Messenger of Allah (sallallahu alayhi wa sallam), is the leader of all messengers.
