Why was the recording of the noble Prophetic Hadiths prohibited for decades, despite the existence of Hadiths such as the one by Abdullah ibn Amr, in which he mentions that the Prophet, peace and blessings be upon him, ordered him to write despite the objection of Quraish?

The Companions differed regarding the writing of Hadith (definition). Some of them disliked it, citing the Hadith: "Do not write anything from me except the Qur’an..." Others permitted it, citing the story of Abu Shah and the narrations of Ali and Abdullah ibn Amr, which confirm their writing. Some scholars believe that the prohibition was out of fear of mixing the Qur’an with the Sunnah (definition), or relying on writing, while permission was granted to those who feared forgetting. This disagreement vanished, and Muslims unanimously agreed on the permissibility of writing. Umar ibn al-Khattab intended to compile the Hadith but later refrained, fearing that people would abandon the Qur’an. The first to generally compile the Sunnah was Umar ibn Abd al-Aziz, who ordered the collection of the Prophet's Hadith, fearing the loss of knowledge. Then, compilation became widespread, and books appeared.
