I have cited this and similar accounts only to evoke astonishment, not to endorse them.
Among his concubines was Māriyah, the mother of Ibrāhīm.
Al-Wāqidī said: Ibn Abī Dhiʾb related to me from al-Zuhrī, who said: “Rayḥānah was a bondwoman of the Messenger of Allah ﷺ. He set her free and then married her. Thereafter she kept herself veiled among her kinsfolk and would say, ‘No one shall see me after the Messenger of Allah ﷺ.’”
Al-Wāqidī added: “This version is the soundest in our view. Rayḥānah’s husband before the Prophet ﷺ was al-Ḥakam, and she belonged to Banū al-Naḍīr. ʿĀṣim ibn ʿAbd Allāh ibn al-Ḥakam narrated to us from ʿUmar ibn al-Ḥakam, who said: The Messenger of Allah ﷺ manumitted Rayḥānah bint Zayd ibn ʿAmr ibn Khunāfah. She was a woman of striking beauty. She herself said, ‘He married me, fixed my dower at twelve uqiyyahs and a nash, consummated the marriage, and allotted me my regular share of nights.’ He was deeply fond of her. She died on his return from the Farewell Pilgrimage, while the marriage contract had been concluded in Muḥarram of the year 6 AH.
ʿAbd Allāh ibn Jaʿfar told me, on the authority of Ibn al-Hād, from Thaʿlabah ibn Abī Mālik: “Rayḥānah was from Banū al-Naḍīr. The Messenger of Allah ﷺ took her captive, then freed her, married her, and she died while still his wife.”
Ibn Wahb said: Yūnus narrated to us from Ibn Shihāb that the Messenger of Allah ﷺ first kept Rayḥānah as a concubine, then emancipated her, whereupon she returned to her people. I (the author) say: This version is closer to the truth and more reliable.
Abū ʿUbaydah said: “The Prophet ﷺ had four female slaves: Māriyah, Rayḥānah of Banū Qurayẓah, Jamīlah—against whom his wives plotted—and another valuable slave-girl whom Zaynab bint Jaḥsh presented to him as a gift.”
Zakariyyā ibn Abī Zāʾidah reported from al-Shaʿbī: “You may put off whomever you will…"
