a wife gives up her marriage rights on her husband in return for staying under his ‘Ismah (the bond of marriage), and they both agree to this, there is no objection to it, because
Sawdah (may Allah be pleased with her) asked the Messenger (peace be upon him) to let her remain in his ‘Ismah in return for giving her night to
‘Aishah (may Allah be pleased with her), and the Prophet (peace be upon him) agreed to this. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
