Sahih Bukhari Volume 9, Book 97, Hadith 7471

حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، حَدَّثَنَا وُهَيْبٌ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ نَبِيَّ اللَّهِ سُلَيْمَانَ ـ عَلَيْهِ السَّلاَمُ ـ كَانَ لَهُ سِتُّونَ امْرَأَةً فَقَالَ لأَطُوفَنَّ اللَّيْلَةَ عَلَى نِسَائِي، فَلْتَحْمِلْنَ كُلُّ امْرَأَةٍ وَلْتَلِدْنَ فَارِسًا يُقَاتِلُ فِي سَبِيلِ اللَّهِ، فَطَافَ عَلَى نِسَائِهِ، فَمَا وَلَدَتْ مِنْهُنَّ إِلاَّ امْرَأَةٌ وَلَدَتْ شِقَّ غُلاَمٍ‏.‏ قَالَ نَبِيُّ اللَّهِ صلى الله عليه وسلم ‏"‏ لَوْ كَانَ سُلَيْمَانُ اسْتَثْنَى لَحَمَلَتْ كُلُّ امْرَأَةٍ مِنْهُنَّ، فَوَلَدَتْ فَارِسًا يُقَاتِلُ فِي سَبِيلِ اللَّهِ ‏"‏‏.‏

Narrated By Abu Huraira : Allah's Prophet Solomon who had sixty wives, once said, "Tonight I will have sexual relation (sleep) with all my wives so that each of them will become pregnant and bring forth (a boy who will grow into) a cavalier and will fight in Allah's Cause." So he slept with his wives and none of them (conceived and) delivered (a child) except one who brought a half (body) boy (deformed). Allah's Prophet said, "If Solomon had said; 'If Allah Will,' then each of those women would have delivered a (would-be) cavalier to fight in Allah's Cause."
