[12][13] In the next month, Muhammad sent Abu Ubaidah ibn al Jarrah along with 300 men to attack and chastise the tribe of Juhaynah at al-Khabat, on the seacoast, five nights journey from Medina.
[14] During this expedition the Muslims' suffered from famine, until they caught a large fish (sperm whale) that came ashore and ate it for twenty days.
[15][16] The Expedition is referenced in the Sunni hadith collection Sahih al-Bukhari as follows: "Allah's Apostle sent an army towards the east coast and appointed Abu 'Ubaida bin Al-Jarrah as their chief, and the army consisted of three-hundred men including myself.
Abu 'Ubaida kept on giving us our daily ration in small amounts from it, till it was exhausted.
So we stayed on the coast for half a month, and were so much afflicted by extreme hunger that we (were obliged) to eat leaves.
and then made him ride over that, and that-tnan passed beneath it (the rib), and many a man could sit in its eye-socket, and we extracted many pitchers of fat from the cavity of its eye.
