"I said, 'Her name is Barra.' She said, 'Change her name. The Prophet (ﷺ) married Zaynab bint Jahsh. Her name was Barra and he changed it to Zaynab. I visited Umm Salama when she married him and my name was Barra. He heard her call me Barra and said, 'Do not adorn yourselves. Allah is the One who knows those who are pious (barra) among you and those who are deviant. Call her Zaynab.' Umm Salama said, 'She is Zaynab.' I said to Zaynab, 'Give her a name.' Zaynab said, 'Change it to what the Messenger of Allah (ﷺ) changed it.'" So he called her Zaynab.
