Abu Hurairah reported,

The Messenger of Allah ﷺ said, "Sulayman said, 'Tonight I will go around to ninety wives, each of whom will bear a horseman who will fight in the cause of Allah.' His companion said to him, 'Say, if Allah wills.' But he did not say, 'If Allah wills.' So he went around to them all, yet none of them conceived except one woman, who gave birth to half a man. By Him in whose hand is Muhammad's soul, had he said, 'If Allah wills,' they would all have ridden out as horsemen fighting in the cause of Allah."

عن أبي هريرة

قال رسول الله ﷺ: قال سليمان: لأطوفن الليلة على تسعين امرأة، كلهن تأتي بفارس يجاهد في سبيل الله، فقال له صاحبه: إن شاء الله، فلم يقل إن شاء الله، فطاف عليهن جميعا فلم يحمل منهن إلا امرأة واحدة، جاءت بشق رجل، وأيم الذي نفس محمد بيده، لو قال: إن شاء الله، لجاهدوا في سبيل الله فرسانا أجمعون.
