باب غَزْوَةُ سِيفِ الْبَحْرِ وَهُمْ يَتَلَقَّوْنَ عِيرًا لِقُرَيْشٍ وَأَمِيرُهُمْ أَبُو عُبَيْدَةَ
Sahih al-Bukhari 4362

Narrated Jabir:

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-`Anbar. 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.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَمْرٌو، أَنَّهُ سَمِعَ جَابِرًا ـ رضى الله عنه ـ يَقُولُ غَزَوْنَا جَيْشَ الْخَبَطِ وَأُمِّرَ أَبُو عُبَيْدَةَ، فَجُعْنَا جُوعًا شَدِيدًا فَأَلْقَى الْبَحْرُ حُوتًا مَيِّتًا، لَمْ نَرَ مِثْلَهُ، يُقَالُ لَهُ الْعَنْبَرُ، فَأَكَلْنَا مِنْهُ نِصْفَ شَهْرٍ، فَأَخَذَ أَبُو عُبَيْدَةَ عَظْمًا مِنْ عِظَامِهِ فَمَرَّ الرَّاكِبُ تَحْتَهُ‏.‏ فَأَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرًا يَقُولُ قَالَ أَبُو عُبَيْدَةَ كُلُوا‏.‏ فَلَمَّا قَدِمْنَا الْمَدِينَةَ ذَكَرْنَا ذَلِكَ لِلنَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏ "‏ كُلُوا رِزْقًا أَخْرَجَهُ اللَّهُ، أَطْعِمُونَا إِنْ كَانَ مَعَكُمْ ‏"‏‏.‏ فَأَتَاهُ بَعْضُهُمْ ‏{‏بِعُضْوٍ‏}‏ فَأَكَلَهُ‏.‏
