I will visit each one of them every night, and every one of them will become pregnant and give birth to a male child who will be a horseman and fight in the cause of Allah. But (it so happened) that none of them became pregnant except one, but she gave birth to an incomplete child. Thereupon Messenger of Allah ﷺ said: Had he said Insha' Allah (if God so wills), then every one of them would have given birth to a child who would have been a horseman and fought in the cause of Allah  

لأَطُوفَنَّ عَلَيْهِنَّ اللَّيْلَةَ فَتَحْمِلُ كُلُّ وَاحِدَةٍ مِنْهُنَّ فَتَلِدُ كُلُّ وَاحِدَةٍ مِنْهُنَّ غُلاَمًا فَارِسًا يُقَاتِلُ فِي سَبِيلِ اللَّهِ فَلَمْ تَحْمِلْ مِنْهُنَّ إِلاَّ وَاحِدَةٌ فَوَلَدَتْ نِصْفَ إِنْسَانٍ فَقَالَ رَسُولُ اللَّهِ ﷺ لَوْ كَانَ اسْتَثْنَى لَوَلَدَتْ كُلُّ وَاحِدَةٍ مِنْهُنَّ غُلاَمًا فَارِسًا يُقَاتِلُ فِي سَبِيلِ اللَّهِ  

I will have an intercourse with seventy wives during the night; all of them will give birth to a male child who will fight in the cause of Allah. His companion or the ang I said to him: Say," If God wills." But he (Hadrat Sulaimin) did not say so, and he forgot it. And none of his wives gave birth to a child, but one who gave birth to a premature child. Messenger of Allah ﷺ said: Had he said Insha' Allah (if God so will). he would not have failed and his desire would have been materialised.  

عَنِ النَّبِيِّ ﷺ قَالَ قَالَ سُلَيْمَانُ بْنُ دَاوُدَ نَبِيُّ اللَّهِ لأَطُوفَنَّ اللَّيْلَةَ عَلَى سَبْعِينَ امْرَأَةً كُلُّهُنَّ تَأْتِي بِغُلاَمٍ يُقَاتِلُ فِي سَبِيلِ اللَّهِ فَقَالَ لَهُ صَاحِبُهُ أَوِ الْمَلَكُ قُلْ إِنْ شَاءَ اللَّهُ فَلَمْ يَقُلْ وَنَسِيَ فَلَمْ تَأْتِ وَاحِدَةٌ مِنْ نِسَائِهِ إِلاَّ وَاحِدَةٌ جَاءَتْ بِشِقِّ غُلاَمٍ فَقَالَ رَسُولُ اللَّهِ ﷺ وَلَوْ قَالَ إِنْ شَاءَ اللَّهُ لَمْ يَحْنَثْ وَكَانَ دَرَكًا لَهُ فِي حَاجَتِهِ  

Abu Huraira reported this hadith from the Messenger of Allah ﷺ through another chain of transmitters.  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ أَوْ نَحْوَهُ  

I will certainly have intercourse with seventy wives during the night, and every wife amongst them will give birth to a child, who will fight in the cause of Allah. It was said to him: Say:" Insha' Allah" (God willing), but he did not say so and forgot it. He went round them but none of them give birth to a child except one woman and that too was an incomplete person. Upon this Messenger of Allah ﷺ said: If he had said" Insha' Allah." he would not have failed, and his desire must have been fulfilled.  

رَسُولُ اللَّهِ ﷺ لَوْ قَالَ إِنْ شَاءَ اللَّهُ لَمْ يَحْنَثْ وَكَانَ دَرَكًا لِحَاجَتِهِ  

I will go round in the night to my ninety wives, and every one of them will give birth to a child (who will grow up) as a horseman and fight in the cause of Allah His companions said to him: Say" Insha' Allah." but he did not say Inshii' Allah. He went round all of them but none of them became pregnant but one, and she gave birth to a premature child. And by Him in Whose hand is the life of Muhammad, if he had said, Insha' Allah (his wives would have given birth to the children who would all have grown up into horsemen and fought in the way of Allah).  

عَنِ النَّبِيِّ ﷺ قَالَ قَالَ سُلَيْمَانُ بْنُ دَاوُدَ لأَطُوفَنَّ اللَّيْلَةَ عَلَى تِسْعِينَ امْرَأَةً كُلُّهَا تَأْتِي بِفَارِسٍ يُقَاتِلُ فِي سَبِيلِ اللَّهِ فَقَالَ لَهُ صَاحِبُهُ قُلْ إِنْ شَاءَ اللَّهُ فَلَمْ يَقُلْ إِنْ شَاءَ اللَّهُ فَطَافَ عَلَيْهِنَّ جَمِيعًا فَلَمْ تَحْمِلْ مِنْهُنَّ إِلاَّ امْرَأَةٌ وَاحِدَةٌ فَجَاءَتْ بِشِقِّ رَجُلٍ وَايْمُ الَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوْ قَالَ إِنْ شَاءَ اللَّهُ لَجَاهَدُوا فِي سَبِيلِ اللَّهِ فُرْسَانًا أَجْمَعُونَ  

" Every one of them giving birth to a child, who would have fought in the cause of Allah."  

عَنْ أَبِي الزِّنَادِ بِهَذَا الإِسْنَادِ مِثْلَهُ غَيْرَ أَنَّهُ قَالَ كُلُّهَا تَحْمِلُ غُلاَمًا يُجَاهِدُ فِي سَبِيلِ اللَّهِ
