It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that once I submitted in the court of the Messenger, "O Messenger of Allah! Should I write down the things I hear from you?" The Noble Prophet, peace and blessings be upon him, said: "Yes!" I asked, "In both states of your pleasure and displeasure?" The Noble Prophet, peace and blessings be upon him, said: "Yes, because nothing except the truth comes out from my tongue."
