We went out in a campaign and the army was called The Army of the Khabt, and Abu 'Ubaida was our commander. We were struck with severe hunger. Then the sea threw a huge dead fish called Al- ʿAnbar, the like of which had never been seen. We ate of it for half a month, and then Abu 'Ubaida took one of its bones (and made an arch of it) so that a rider could easily pass under it.  

أَنَّهُ سَمِعَ جَابِرًا ؓ يَقُولُ غَزَوْنَا جَيْشَ الْخَبَطِ وَأُمِّرَ أَبُو عُبَيْدَةَ فَجُعْنَا جُوعًا شَدِيدًا فَأَلْقَى الْبَحْرُ حُوتًا مَيِّتًا لَمْ يُرَ مِثْلُهُ يُقَالُ لَهُ الْعَنْبَرُ فَأَكَلْنَا مِنْهُ نِصْفَ شَهْرٍ فَأَخَذَ أَبُو عُبَيْدَةَ عَظْمًا مِنْ عِظَامِهِ فَمَرَّ الرَّاكِبُ تَحْتَهُ  

We set out in the army of Al-Khabt and Abu Ubaida was the commander of the troops. We were struck with severe hunger and the sea threw out a dead fish the like of which we had never seen, and it was called Al-ʿAnbar. We ate of it for half a month. Abu Ubaida took (and fixed) one of its bones and a rider passed underneath it (without touching it). (Jabir added:) Abu 'Ubaida said (to us), "Eat (of that fish)." When we arrived at Medina, we informed the Prophet ﷺ about that, and he said, "Eat, for it is food Allah has brought out for you, and feed us if you have some of it." So some of them gave him (of that fish) and he ate it. (Using translation from Bukhārī 4362)   

يُقَالُ لَهُ الْعَنْبَرُ فَأَكَلْنَا مِنْهُ نِصْفَ شَهْرٍ فَأَخَذَ أَبُو عُبَيْدَةَ ؓ عَظْمًا مِنْ عِظَامِهِ فَمَرَّ الرَّاكِبُ تَحْتَهُ قَالَ ابْنُ جُرَيْجٍ وَأَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرًا ؓ يَقُولُ فَقَالَ أَبُو عُبَيْدَةَ كُلُوا فَلَمَّا قَدِمْنَا ذَكَرْنَا ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ كُلُوا رِزْقًا
