Sahih Muslim 7520

وَشَكَا النَّاسُ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْجُوعَ فَقَالَ عَسَى اللَّهُ أَنْ يُطْعِمَكُمْ فَأَتَيْنَا سِيفَ الْبَحْرِ فَزَخَرَ الْبَحْرُ زَخْرَةً فَأَلْقَى دَابَّةً فَأَوْرَيْنَا عَلَى شِقِّهَا النَّارَ فَاطَّبَخْنَا وَاشْتَوَيْنَا وَأَكَلْنَا حَتَّى شَبِعْنَا قَالَ جَابِرٌ فَدَخَلْتُ أَنَا وَفُلَانٌ وَفُلَانٌ حَتَّى عَدَّ خَمْسَةً فِي حِجَاجِ عَيْنِهَا مَا يَرَانَا أَحَدٌ حَتَّى خَرَجْنَا فَأَخَذْنَا ضِلَعًا مِنْ أَضْلَاعِهِ فَقَوَّسْنَاهُ ثُمَّ دَعَوْنَا بِأَعْظَمِ رَجُلٍ فِي الرَّكْبِ وَأَعْظَمِ جَمَلٍ فِي الرَّكْبِ وَأَعْظَمِ كِفْلٍ فِي الرَّكْبِ فَدَخَلَ تَحْتَهُ مَا يُطَأْطِئُ رَأْسَهُ

Then the people made a complaint to Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) about hunger and he said: May Allah provide you food! We came to the bank of the ocean and the ocean was tossing and it threw out a big animal and we lit fire and cooked it and took it until we had eaten to our heart's content. Jabir said: I and such and such five persons entered Its socket and nobody could see us until we had come out, and we took hold of one of its ribs and twisted it into a sort of arch, then we called the tallest of the persons of the army and the hugest of the camels of the army and it had the big saddle over it, and it could easily pass through it without the rider having need to bend down.
