خديجة بنت خويلد
Around 625 Muhammad proposed to Zaynab that she marry his adopted son, Zayd ibn Harithah. Zayd had been born into the Kalb tribe but as a child he had been kidnapped by slave-traders. He had been sold to a nephew of Khadija bint Khuwaylid, who in her turn had given him as a wedding present to her husband Muhammad. After some years, Muhammad had manumitted Zayd and had adopted him as his son.
