Is remembering the birth of the Prophet, peace and blessings be upon him, every Monday by reading his biography individually or in a group, and fasting on that day because it is the day he was born, considered an innovation, especially since there is no evidence that the people of the virtuous generations did so?

"Fasting on Mondays is legislated and desirable. The Prophet, peace and blessings be upon him, explained that he fasted on this day because it was the day he was born and the revelation descended upon him. Also, because deeds are presented to Allah on this day, and he loved for his deeds to be presented while he was fasting. As for reading the Sirah (Prophet's biography) on this day under the pretext that it is the day of his birth, this is not from the guidance of the Salaf (pious predecessors), and it is more proper to follow their guidance."
