Wahb bin Munabbih narrated from his brother that he heard Sayyiduna Abu Hurairah (may Allah be pleased with him) say: There is no one among the companions of the Messenger of Allah (peace be upon him) who has more of his hadith than I do, except for Sayyiduna Abdullah bin Amr (may Allah be pleased with him), because he used to write them down and I did not write.

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."

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! I wish to narrate your hadith, so if you consider it appropriate, I intend to assist my heart with the writing of my hand as well. The Messenger of Allah (peace and blessings be upon him) said: "First, memorize my hadith well, then assist your heart with the writing of your hand as well."

Abu Qabeel said: I heard Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) say: We were sitting around the Messenger of Allah (peace and blessings be upon him) writing, when suddenly the Messenger of Allah (peace and blessings be upon him) was asked: Which city will be conquered first, Constantinople or Rome? The Noble Prophet (peace and blessings be upon him) replied: "No, the city of Heraclius will be conquered first." (That is, Rome).

Abdullah bin Dinar said: Umar bin Abdul Aziz, may Allah have mercy on him, wrote to Abu Bakr bin Muhammad bin Amr bin Hazm that whatever established hadith of the Messenger of Allah, peace and blessings be upon him, and from 'Umrah you have, write it and send it to us, because I fear the disappearance and loss of knowledge.

Abdullah bin Dinar said that Umar bin Abdul Aziz, may Allah have mercy on him, wrote to the people of Madinah to search for the hadith of the Messenger of Allah, peace and blessings be upon him, and write it down. He said, "I fear the disappearance of knowledge and the loss or departure of the people of knowledge."

Abu Miliḥ (Usama bin Umair) said: People find fault with us for writing, although Allah Almighty says: «﴿ عِلْمُهَا عِنْدَ رَبِّي فِي كِتَابٍ ﴾» [طه: 52/20] meaning, "Its knowledge is written with my Lord."

Sawadah bin Hibban narrated that I heard Abu Ayyas Muawiyah bin Qurrah say: Whoever does not record his knowledge, his knowledge will not remain knowledge.

Abdullah bin al-Muthanna said: Thumamah bin Anas narrated to me that Sayyiduna Anas (may Allah be pleased with him) used to say to his sons: O my sons! Preserve this knowledge, that is, write it down.

Muslim bin Qais Al-Alawi said: I saw Aban (ibn Abi Ayyash) writing on a (board) tablet in the presence of Sayyiduna Anas (may Allah be pleased with him).
