What was the revelation that descended upon our Prophet Muhammad on the day of his death, and to which Anas referred when he said: "Indeed, Allah, عز وجل (the Mighty and Majestic), continued to send down revelation upon the Messenger of Allah before his death, until he passed away, and the most revelation he received was on the day the Messenger of Allah, may Allah bless him and grant him peace, died"?

The revelation continued to descend upon the Messenger of Allah, peace and blessings be upon him, until Allah took his soul. This was due to the large number of delegations and those inquiring about rulings after the conquest of Mecca, which necessitated the revelation of legal rulings. This was not exclusive to the day of his death, but rather encompassed the last period of his life, during which the religion was perfected and all rulings were revealed.
