Why did the Prophet (peace and blessings be upon him) prohibit writing down the Sunnah?

Question:
Benefits of the explanation of the book *Iqtida' al-Sirat al-Mustaqim li-Mukhalafat Ahl al-Jahim* by Ibn Taymiyyah. Shaykh, naturally, given the difference between the Qur'an and the Sunnah, is it permissible for anyone to wish that the Companions had also written down the Sunnah? Is it permissible for anyone to wish for that? That is, if only 'Umar or Uthman had stood for a month seeking guidance from Allah to write down the Sunnah?

Answer:
The Messenger (peace and blessings be upon him) prohibited the writing of hadiths during his lifetime (peace and blessings be upon him) so that the Qur'an would not be mixed with the Sunnah. When the Prophet (peace and blessings be upon him) passed away, this danger was removed because revelation had ceased and ended; revelation ended and the revelation of the Qur'an ended, so the danger was removed. Therefore, they began to record and write down the Sunnah. During the time of the Prophet (peace and blessings be upon him), there were those who wrote, but they wrote only for themselves, specifically for their own personal use. As for public writing, that only occurred after the death of the Messenger (peace and blessings be upon him), because the danger had ended, because revelation had ended, and the Qur'an, praise be to Allah, was completed, and the religion was completed. At that point, the danger was removed. When they feared the loss of the Sunnah, they proceeded to collect, record, and organize it.
