Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The mother of Abu Bakr, the mother of Uthman, the mother of Talhah, the mother of al-Zubayr, the mother of Abd al-Rahman bin Awf, and the mother of Ammar bin Yasir (may Allah be pleased with them) all accepted Islam. And it is said: Atiq bin Uthman; he was called Atiq only because of the beauty of his face.
