Sunan an-Nasa'i, Volume 5, Book 42, Hadith 4356 (DarusSalam) ⓘ

It was narrated that Jabir bin 'Abdulah saida: "The Prophet sent us, a group of three hundred, and we carried our provision on our mounts. Our supplies ran our until each man of us had one date per day." It was said to him: "O Abu'Abdullah, what good is one date for a man?" he said: "When we ran out of dates it became very difficult for us. Then we found a whale that had been cast ashore by the sea. And we ate from it for eight days."

أَخْبَرَنَا مُحَمَّدُ بْنُ آدَمَ، قَالَ حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامٍ، عَنْ وَهْبِ بْنِ كَيْسَانَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ بَعَثَنَا النَّبِيُّ صلى الله عليه وسلم وَنَحْنُ ثَلاَثُمِائَةٍ نَحْمِلُ زَادَنَا عَلَى رِقَابِنَا فَفَنِيَ زَادُنَا حَتَّى كَانَ يَكُونُ لِلرَّجُلِ مِنَّا كُلَّ يَوْمٍ تَمْرَةٌ ‏.‏ فَقِيلَ لَهُ يَا أَبَا عَبْدِ اللَّهِ وَأَيْنَ تَقَعُ التَّمْرَةُ مِنَ الرَّجُلِ قَالَ لَقَدْ وَجَدْنَا فَقْدَهَا حِينَ فَقَدْنَاهَا فَأَتَيْنَا الْبَحْرَ فَإِذَا بِحُوتٍ قَذَفَهُ الْبَحْرُ فَأَكَلْنَا مِنْهُ ثَمَانِيَةَ عَشَرَ يَوْمًا ‏.‏
