BŪRĀN, (Middle Pers. Bōrān) also called Ḵadīja (192-271/807-84), wife of al-Maʾmūn and daughter of Ḥasan b. Sahl, was probably so named after the Sasanian queen Bōrān (r. 29-30). At the age of ten she was betrothed to al-­Maʾmūn, but the wedding took place at her father’s residence in Fam al-Ṣelḥ near Wāseṭ when she was almost eighteen (Ramażān, 210/December, 825-­January, 826). The occasion was so pompously celebrated that it became proverbial and won the name of “The Invitation of Islam,” Daʿwat al-Eslām (cf. Ṯaʿālebī, Ṯemār al-qolūb, Cairo, 1965, pp. 165). She is also remembered for asking the caliph to pardon his uncle Ebrāhīm b. Mahdī and to allow Zobayda to go on pilgrimage. Nothing else is known about her as a queen (210-18/825-33) or during her long life after the death of al-Maʾmūn (218/833). She died (Rabīʿ I, 271/Septem­her, 884) in the former palace of Jaʿfar Barmakī on the Tigris (al-Qaṣr al-Ḥasanī), which she had received from her father. She is credited with the creation of the popular dish būrānī (see Naḵjavānī, p. 145).
