The Prophet Muhammad (SAW) passed away in the year 632 C.E. This is a well-established fact in Islamic history and is widely accepted by Muslim scholars and historians. The exact date of his death is the 12th of Rabi' al-Awwal, which is the third month in the Islamic lunar calendar.
The year 610 C.E. marks the beginning of the Prophet's revelation when he received the first verses of the Quran from the Angel Gabriel. This event is known as the Night of Power or Laylat al-Qadr in Arabic. Therefore, it is not the year of his death.
On the other hand, the years 519 C.E. and 517 C.E. are not relevant to the Prophet's life or death, as they are many years before his birth.
