Ismaili History 311 - The Year of Grief
In the year 619 A.D., not long after annulment of the social boycott, Muhammad suffered a great loss of Abu Talib and Khadija, who followed each other to meet their deaths within a short interval, which was a severe blow. With the death of Khadija, the lamp of Muhammad's home was extinguished. One protected him with the influence that derived from his noble rank, while the other guarded him with her material and wealth. After the death of Abu Talib and Khadija, Muhammad was immersed in deep grief, and that is why, this year is called aam-ul-huzn (the year of grief). The bereavement of his uncle and wife cast a gloom over Muhammad's life. The tragedy coincided with so many afflictions and animosities of his enemies that Mecca had become a bed of thorns for Muhammad by now onwards.
