Khadijah bint Khuwaylid (may Allah be pleased with her): Khadijah died a year before the Hijrah

It is narrated from Imam al-Zuhri (may Allah have mercy on him) that the first woman whom the Messenger of Allah (peace and blessings be upon him) married was Sayyidah Khadijah bint Khuwaylid bin Asad bin Abd al-Uzza. He (peace and blessings be upon him) married her in the period of Jahiliyyah, and her father, Khuwaylid bin Asad, gave her in marriage.

Dawud bin Muhammad bin Abi Ma'shar narrates from his father, who narrates from his grandfather, that Sayyidah Khadijah (may Allah be pleased with her) died one year before the Hijrah.

It is narrated from Muhammad bin Ishaq that Abu Talib and Khadijah bint Khuwaylid (may Allah be pleased with her) died in the same year, and that was three years before the Prophet's (peace and blessings be upon him) emigration to Madinah. Sayyidah Khadijah (may Allah be pleased with her) was buried at al-Hajun (cemetery), and the Messenger of Allah (peace and blessings be upon him) himself went down into her grave. At the time he (peace and blessings be upon him) married her, she was 28 years old. Muhammad bin Ishaq said: The kunyah of Sayyidah Khadijah was Umm Hind. At the time of her marriage to the Messenger of Allah (peace and blessings be upon him), she had a son and a daughter. Khadijah's mother was Fatimah bint Za'idah bin al-Asamm, and her mother was Halah bint Abd Manaf.
