The Holy Prophet Muhammad ﷺ was born in the same year in which Abraha of Yemen attacked the Ka‘bah. Historian Mahmud Pasha Falki, the renowned mathematician, has calculated this year to be 571 CE, agreed upon by many authentic works on the history of Arabia. The date is said to be around 20 April on the Gregorian calendar, while the dates marked on the Islamic calendar are estimated to be on or between 9 and 12 Rabi‘ al-Awwal.
