Jabir bin Abdullah reported,

The Messenger of Allah ﷺ dispatched an expedition toward the coast and placed Abu Ubayda bin al-Jarrah in command. We were three hundred men, and I was among them. We set out, and when we had covered part of the journey, our provisions ran out. Abu Ubayda ordered that the supplies of the army be gathered together, and it all came to two sacks of dates. He would ration them out to us little by little each day until they were nearly gone, and then we received only a single date each.I said, "What good can a single date do?"He replied, "We have come to feel its loss now that it is finished."Then we reached the sea, and there we found a fish like a small mountain. The army ate from it for eighteen nights. Then Abu Ubayda ordered that two of its ribs be set up. They were planted in the ground, and he ordered a riding camel to be saddled, and it passed beneath them without touching them.

Sahih

عن جابر بن عبد الله أنه قال

بعث رسول الله ﷺ بعثا قبل الساحل، فأمر عليهم أبا عبيدة بن الجراح، وهم ثلاث مائة، وأنا فيهم، فخرجنا حتى إذا كنا ببعض الطريق، فني الزاد، فأمر أبو عبيدة بأزواد ذلك الجيش، فجمع ذلك كله فكان مزودي تمر، فكان يقوتنا كل يوم قليلا قليلا حتى فني فلم يكن يصيبنا إلا تمرة تمرة فقلت: وما تغني تمرة فقال: لقد وجدنا فقدها حين فنيت، قال: ثم انتهينا إلى البحر، فإذا حوت مثل الظرب، فأكل منه ذلك الجيش ثماني عشرة ليلة، ثم أمر أبو عبيدة بضلعين من أضلاعه فنصبا ثم أمر براحلة، فرحلت ثم مرت تحتهما، فلم تصبهما.
