Amr, Jabir bin Abdullah reported,

The Messenger of Allah ﷺ sent us out, three hundred riders strong, with Abu Ubayda bin Jarra as our commander, to lie in wait for a caravan of Quraysh. We stayed on the coast for half a month and were struck by such severe hunger that we ate khabat leaves, which is why it was called the Army of Khabat.Then the sea cast up for us a creature called the Anbar, and we ate from it for half a month and oiled ourselves with its fat until our bodies regained their strength.Abu Ubayda took one of its ribs and set it upright, then he looked for the tallest man in the army and the tallest camel, mounted the man on the camel, and he passed beneath it. A group of men sat inside the socket of its eye, and we extracted such-and-such number of jars of oil from the hollow of its eye.We had with us a sack of dates, and Abu Ubayda used to give each man a handful at a time, then later he gave us one date at a time, and when they ran out we felt their loss.

حدثنا عبد الجبار بن العلاء حدثنا سفيان قال

سمع عمرو جابر بن عبد الله يقول

ا بعثنا رسول الله ﷺ ونحن ثلاث مائة راكب وأميرنا أبو عبيدة بن الجراح نرصد عيرا لقريش فأقمنا بالساحل نصف شهر فأصابنا جوع شديد حتى أكلنا الخبط فسمي جيش الخبط فألقى لنا البحر دابة يقال لها العنبر فأكلنا منها نصف شهر وادهنا من ودكها حتى ثابت أجسامنا قال فأخذ أبو عبيدة ضلعا من أضلاعه فنصبه ثم نظر إلى أطول رجل في الجيش وأطول جمل فحمله عليه فمر تحته قال وجلس في حجاج عينه نفر قال وأخرجنا من وقب عينه كذا وكذا قلة ودك قال وكان معنا جراب من تمر فكان أبو عبيدة يعطي كل رجل منا قبضة قبضة ثم أعطانا تمرة تمرة فلما فني وجدنا فقده
