She said: Change her name; for the Prophet, peace be upon him, married Zaynab bint Jahsh and her name was Barra, so he changed her name to Zaynab. He entered upon Umm Salama when he married her, and my name was Barra, and he heard her calling me: Barra, so he said: "Do not ascribe purity to yourselves; for Allah is most knowing of the righteous among you and the wicked.
