Narrated 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 ﷺ 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." (See Hadith No. 74 A, Vol. 4).

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 ﷺ
" لَوْ كَانَ سُلَيْمَانُ اسْتَثْنَى لَحَمَلَتْ كُلُّ امْرَأَةٍ مِنْهُنَّ، فَوَلَدَتْ فَارِسًا يُقَاتِلُ فِي سَبِيلِ اللَّهِ ".
