Ibn ‘Awn said “I wrote to Nafi’ asking him about summoning the polytheists (to Islam) at the time of fighting. So, he wrote to me “This was in the early days of Islam. The Prophet of Allaah ﷺ attacked Banu Al Mustaliq while they were inattentive and their cattle were drinking water. So their fighters were killed and the survivors (i.e., women and children) were taken prisoners. On that day Juwairiyyah daughter of Al Harith was obtained. ‘Abd Allaah narrated this to me, he was in that army.” Abu Dawud said “This is a good tradition narrtted by Ibn ‘Awn from Nafi’ and no one shared him in narrating it.” (Using translation from Abū Dāʾūd 2633)   

عَنِ الدُّعَاءِ يَعْنِي فِي الْقِتَالِ فَكَتَبَ إِنَّمَا كَانَ ذَلِكَ فِي أَوَّلِ الْإِسْلَامِ قَدْ أَغَارَ رَسُولُ اللهِ ﷺ عَلَى بَنِي الْمُصْطَلِقِ وَهُمْ غَارُّونَ وَأَنْعَامُهُمْ تُسْقَى عَلَى الْمَاءِ فَقَتَلَ مُقَاتِلَتَهُمْ وَسَبَى سَبْيَهُمْ وَأَصَابَ يَوْمَئِذٍ جُوَيْرِيَةَ بِنْتَ الْحَارِثِ حَدَّثَنِي بِذَلِكَ عَبْدُ اللهِ بْنُ عُمَرَ وَكَانَ فِي ذَلِكَ الْجَيْشِ  

[Machine] So he wrote: "Indeed, that happened in the early days of Islam, when the Messenger of Allah ﷺ was jealous of the Banu Mustaliq tribe, while they were watering their livestock. He killed their warriors, captured their captives, and on that day he had what I believe was Juwayriyah bint al-Harith narrate this incident to me. Abdullah ibn Umar was in that army."  

فَكَتَبَ إِنَّمَا كَانَ ذَاكَ فِي أَوَّلِ الْإِسْلَامِ قَدْ أَغَارَ رَسُولُ اللهِ ﷺ عَلَى بَنِي الْمُصْطَلِقِ وَهُمْ غَارُّونَ وَأَنْعَامُهُمْ تُسْقَى عَلَى الْمَاءِ فَقَتَلَ مُقَاتِلَتَهُمْ وَسَبَى سَبْيَهُمْ وَأَصَابَ يَوْمَئِذٍ أَحْسَبُهُ قَالَ جُوَيْرِيَةَ بِنْتَ الْحَارِثِ حَدَّثَنِي بِهَذَا الْحَدِيثِ عَبْدُ اللهِ بْنُ عُمَرَ وَكَانَ فِي ذَلِكَ الْجَيْشِ  

I wrote to Nafi' inquiring from him whether it was necessary to extend (to the disbelievers) an invitation to accept (Islam) before meeting them in fight. He wrote (in reply) to me that it was necessary in the early days of Islam. The Messenger of Allah ﷺ made a raid upon Banu Mustaliq while they were unaware and their cattle were having a drink at the water. He killed those who fought and imprisoned others. On that very day, he captured Juwairiya bint al-Harith. Nafi' said that this tradition was related to him by Abdullah b. Umar who (himself) was among the raiding troops. (Using translation from Muslim 1730a)   

فَكَتَبَ إِنَّمَا كَانَ ذَلِكَ فِي أَوَّلِ الْإِسْلَامِ قَدْ أَغَارَ رَسُولُ اللهِ ﷺ عَلَى بَنِي الْمُصْطَلِقِ وَهُمْ غَارُّونَ وَأَنْعَامُهُمْ تُسْقَى عَلَى الْمَاءِ فَقَتَلَ مُقَاتِلَتَهُمْ وَسَبَى سَبْيَهُمْ وَأَصَابَ يَوْمَئِذٍ قَالَ يَحْيَى أَحْسِبُهُ قَالَ جُوَيْرِيَةُ بِنْتُ الْحَارِثِ وَحَدَّثَنِي بِهَذَا الْحَدِيثِ عَبْدُ اللهِ بْنُ عُمَرَ وَكَانَ فِي ذَلِكَ الْجَيْشِ
