Sahih al-Bukhari 2483
Narrated Jabir bin `Abdullah:
"Allah's Messenger (ﷺ) sent an army towards the east coast and appointed Abu 'Ubaida bin Al-Jarrah as their 
chief, and the army consisted of three-hundred men including myself. We marched on till we reached 
a place where our food was about to finish. Abu- 'Ubaida ordered us to collect all the journey food and 
it was collected. My (our) journey food was dates. Abu 'Ubaida kept on giving us our daily ration in 
small amounts from it, till it was exhausted. The share of everyone of us used to be one date only." I 
said, "How could one date benefit you?" Jabir replied, "We came to know its value when even that too 
finished." Jabir added, "When we reached the sea-shore, we saw a huge fish which was like a small 
mountain. The army ate from it for eighteen days. Then Abu 'Ubaida ordered that two of its ribs be 
fixed and they were fixed in the ground. Then he ordered that a she-camel be ridden and it passed 
under the two ribs (forming an arch) without touching them."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ وَهْبِ بْنِ كَيْسَانَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ أَنَّهُ قَالَ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَعْثًا قِبَلَ السَّاحِلِ، فَأَمَّرَ عَلَيْهِمْ أَبَا عُبَيْدَةَ بْنَ الْجَرَّاحِ وَهُمْ ثَلاَثُمِائَةٍ وَأَنَا فِيهِمْ، فَخَرَجْنَا حَتَّى إِذَا كُنَّا بِبَعْضِ الطَّرِيقِ فَنِيَ الزَّادُ، فَأَمَرَ أَبُو عُبَيْدَةَ بِأَزْوَادِ ذَلِكَ الْجَيْشِ فَجُمِعَ ذَلِكَ كُلُّهُ فَكَانَ مِزْوَدَىْ تَمْرٍ، فَكَانَ يُقَوِّتُنَا كُلَّ يَوْمٍ قَلِيلاً قَلِيلاً، حَتَّى فَنِيَ فَلَمْ يَكُنْ يُصِيبُنَا إِلاَّ تَمْرَةٌ تَمْرَةٌ‏.‏ فَقُلْتُ وَمَا تُغْنِي تَمْرَةٌ فَقَالَ لَقَدْ وَجَدْنَا فَقْدَهَا حِينَ فَنِيَتْ‏.‏ قَالَ ثُمَّ انْتَهَيْنَا إِلَى الْبَحْرِ فَإِذَا حُوتٌ مِثْلُ الظَّرِبِ، فَأَكَلَ مِنْهُ ذَلِكَ الْجَيْشُ ثَمَانِيَ عَشْرَةَ لَيْلَةً، ثُمَّ أَمَرَ أَبُو عُبَيْدَةَ بِضِلَعَيْنِ مِنْ أَضْلاَعِهِ فَنُصِبَا، ثُمَّ أَمَرَ بِرَاحِلَةٍ فَرُحِلَتْ ثُمَّ مَرَّتْ تَحْتَهُمَا فَلَمْ تُصِبْهُمَا‏.‏
