It was narrated that Jabir said:"The Prophet sent us with Abu 'Ubaidah on a campaign. Our supplies ran out. Then we passed by a whale that had been cast ashore by the sea. We wanted to eat from it, but Abu 'Ubaidah told us not to. Then he said: 'We are the envoys of the Messenger of Allah for the sake of Allah, so eat. So we ate from it for several days. When we came to the messenger of Allah we told him about that and he said: 'If you have anything left of it then send it to us."'
أَخْبَرَنَا زِيَادُ بْنُ أَيُّوبَ، قَالَ حَدَّثَنَا هُشَيْمٌ، قَالَ حَدَّثَنَا أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ بَعَثَنَا النَّبِيُّ صلى الله عليه وسلم مَعَ أَبِي عُبَيْدَةَ فِي سَرِيَّةٍ فَنَفِدَ زَادُنَا فَمَرَرْنَا بِحُوتٍ قَدْ قَذَفَ بِهِ الْبَحْرُ فَأَرَدْنَا أَنْ نَأْكُلَ مِنْهُ فَنَهَانَا أَبُو عُبَيْدَةَ ثُمَّ قَالَ نَحْنُ رُسُلُ رَسُولِ اللَّهِ صلى الله عليه وسلم وَفِي سَبِيلِ اللَّهِ كُلُوا . فَأَكَلْنَا مِنْهُ أَيَّامًا فَلَمَّا قَدِمْنَا عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم أَخْبَرْنَاهُ فَقَالَ " إِنْ كَانَ بَقِيَ مَعَكُمْ شَىْءٌ فَابْعَثُوا بِهِ إِلَيْنَا " .
