[Machine] Abu Ayub witnessed the Battle of Badr with the Messenger of Allah ﷺ , and he did not miss any of the Muslim military expeditions except for one year. He was appointed as a young man in the army that year, so he stayed back. After that, he became eager and would say, "I do not want to be left behind when I am called upon." Then he fell ill while Yazid ibn Muawiya was leading the army. He went to visit him and asked, "What do you need?" Abu Ayub replied, "If I die, put me on a mount and continue to advance into the enemy's land until you find a suitable place. If you do not find a suitable place, bury me and then return." Abu Ayub used to say that Allah Almighty stated in the Quran, "March forth, whether light or heavy." (Surah At-Tawbah, 9:41) Al-Dhahabi did not mention this narration in his summarized version.  

شَهِدَ أَبُو أَيُّوبَ مَعَ رَسُولِ اللَّهِ ﷺ بَدْرًا ثُمَّ لَمْ يَتَخَلَّفْ عَنْ غَزَاةِ الْمُسْلِمِينَ إِلَّا هُوَ فِيهَا إِلَّا عَامًا وَاحِدًا فَإِنَّهُ اسْتُعْمِلَ عَلَى الْجَيْشِ رَجُلٌ شَابٌّ فَقَعَدَ ذَلِكَ الْعَامَ فَجَعَلَ بَعْدَ ذَلِكَ يَتَلَهَّفُ وَيَقُولُ مَا عَلَيَّ مَنِ اسْتُعْمِلَ فَمَرِضَ وَعَلَى الْجَيْشِ يَزِيدُ بْنُ مُعَاوِيَةَ فَدَخَلَ عَلَيْهِ يَعُودُهُ فَقَالَ مَا حَاجَتُكَ؟ فَقَالَ «حَاجَتِي إِذَا أَنَا مُتُّ فَارْكَبْ ثُمَّ اسْعَ فِي أَرْضِ الْعَدُوِّ مَا وَجَدْتَ مَسَاغًا فَإِذَا لَمْ تَجِدْ مَسَاغًا فَادْفِنِّي ثُمَّ ارْجِعْ» قَالَ وَكَانَ أَبُو أَيُّوبَ يَقُولُ قَالَ اللَّهُ ﷻ {انْفِرُوا خِفَافًا وَثِقَالًا} [التوبة 41] «فَلَا أَجِدُنِي إِلَّا خَفِيفًا أَوْ ثَقِيلًا» سكت عنه الذهبي في التلخيص
