The History of Humāyūn (Gulbadan Begam) 79: XCI. Khadija Begam.

79

Presumably she was named after Muhammad's first wife.
She was first a slave of Sultan Abu-sa'id Mirza, and upon his death in 873H. (1469) she betook herself to Harat and there became the wife of Sultan Husain Bayqra.
She had a daughter, known as Aq Begam, by Abu-sa'id, and two sons, Shah Gharib and Muzaffar Husain, by her marriage with Husain.
Hers is an instance where the conferring of a title is mentioned. Babar says that Husain was passionately fond of her and that he raised her to the rank of begam; also that she managed him entirely. To her are attributed the intrigues and rebellion which ruined Husain’s family. She acquired more influence than any other of his wives, and it was consequently round her surviving son Muzaffar Husain, that adherents gathered after his father’s death. She forced on the joint-kingship which excited Babar’s ridicule. Mirza Haidar when speaking of the death of Jahangir Madr-shahi, said that he was generally reported to have been poisoned in his wine by Khadija Begam after her old fashion.
In 912H. (1506-7) Babar saw her in Harat, and he was there unlawfully entertained by her at a wine-party. When Shaibani conquered the city in 913H. she was cast down from her high estate and given up to be plundered, and was treated as one of Shaibani’s meanest slaves.

Muharram 6th, 935H (September 20th, 1528), but various business detained her and Babar paid her another of his dutiful visits on October 9th When or if she returned to Kabul is not said, but she was at the Mystic Feast in Agra in 1531 Gul-badan, 11a, 246 Mems., 374, 382, 387.
