Zaynab bint Maẓʿūn (Arabic: زينب بنت مظعون) was the first wife of Umar.
[3]: 510 Umar said that Quraysh men at that time "had the upper hand over their wives," and "did not pay attention to women".
[4] Zaynab's attitude to Islam is unknown and the date of her eventual conversion is not recorded.
[3]: 218 One tradition asserts that Zaynab had died by then; however, her son Abd Allah said that he had emigrated to Medina with both his parents.
In 628 Umar divorced Umm Kulthum and Qurayba because of a new instruction, that a Muslim could not remain married to a polytheist.
