"I was next to Zaid bin Arqam when he was asked: 'How many battles did the Prophet ﷺ fight ?' He said: 'Nineteen.' So I said: 'How many battles did you take part in with him ?' he said: 'Seventeen.' I said: 'Which of them was the first?' He said: 'Dhat Al-Ushaira' or Al-'Usaira'. '"  

كُنْتُ إِلَى جَنْبِ زَيْدِ بْنِ أَرْقَمَ فَقِيلَ لَهُ كَمْ غَزَا النَّبِيُّ ﷺ مِنْ غَزْوَةٍ قَالَ تِسْعَ عَشْرَةَ فَقُلْتُ كَمْ غَزَوْتَ أَنْتَ مَعَهُ قَالَ سَبْعَ عَشْرَةَ قُلْتُ أَيَّتُهُنَّ كَانَ أَوَّلَ قَالَ ذَاتُ الْعُشَيْرَاءِ أَوِ الْعُسَيْرَاءِ  

[Machine] I met Zaid bin Arqam and asked him, "How many battles did the Messenger of Allah ﷺ participate in?" He replied, "Nineteen." I then asked him, "How many battles did you participate in with him?" He replied, "Seventeen battles." I asked further, "Which was the first battle the Prophet ﷺ fought?" He replied, "The Battle of 'Ushayrah."  

لَقِيتُ زَيْدَ بْنَ أَرْقَمَ فَقُلْتُ كَمْ غَزَا رَسُولُ اللهِ ﷺ؟ قَالَ تِسْعَ عَشْرَةَ قُلْتُ كَمْ غَزَوْتَ أَنْتَ مَعَهُ؟ قَالَ سَبْعَ عَشْرَةَ غَزْوَةً قَالَ فَقُلْتُ فَمَا أَوَّلُ غَزْوَةٍ غَزَا؟ قَالَ ذَاتُ الْعُشَيْرِ أَوِ الْعُشَيْرَةِ  

[Machine] Abdullah ibn Yazid al-Ansari went out to seek rain from the people. He then prayed two rak'ahs and sought rain. On that day, I met Zaid ibn Arqam, and there was no one between him and me except one man. I asked him, "How many battles did the Messenger of Allah ﷺ wage?" He said, "Nineteen battles." I asked, "How many battles did you participate in with him?" He said, "Seventeen battles." I asked, "Which was the first battle that he fought?" He said, "The Battle of Ushayrah or the Battle of Ushayra."  

عَنْ عَبْدِ اللهِ بْنِ يَزِيدَ الْأَنْصَارِيِّ خَرَجَ يَسْتَسْقِي بِالنَّاسِ فَصَلَّى رَكْعَتَيْنِ ثُمَّ اسْتَسْقَى فَلَقِيتُ يَوْمَئِذٍ زَيْدَ بْنَ أَرْقَمَ وَلَيْسَ بَيْنِي وَبَيْنَهُ غَيْرُ رَجُلٍ أَوْ بَيْنِي وَبَيْنَهُ رَجُلٌ قُلْتُ كَمْ غَزَا رَسُولُ اللهِ ﷺ؟ قَالَ تِسْعَ عَشْرَةَ غَزْوَةً قُلْتُ كَمْ غَزَوْتَ أَنْتَ مَعَهُ؟ قَالَ سَبْعَ عَشْرَةَ قُلْتُ فَمَا أَوَّلُ غَزْوَةٍ غَزَاهَا؟ قَالَ ذَاتُ الْعُسَيْرَةِ أَوْ ذَاتِ الْعُشَيْرَةِ
