In the tenth year of Prophethood, the Prophet’s uncle Abu Talib, who had given him constant support, and his wife Khadija, with whom he had shared a happy life for twenty-five years, passed away only three days apart from one another (10 Ramadan/19 April 620). Their demise deeply saddened the Prophet and the Muslims. Thus, this year came to be known as the Year of Sorrow.
