Sahih Muslim Bk 21, Number 4757:
Jabir b. 'Abdullah reported: Allah's Messenger (may peace he upon him) sent us (on an expedition). We were three hundred riders and our chief (leader) was 'Ubaida b. al−Jarrah. We were on the look out for a caravan of the Quraish. 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. That is why it was called the Detachment of the Leaves. The ocean cast out for us an animal which was called al−'Anbar (whale). We ate of that for half of the month and rubbed its fat on our (bodies) until our bodies became stout. Abu 'Ubaida caught hold of one of its ribs and fixed that up. He then cast a glance at the tallest man of the army and the highest of the camels. 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. We had small bags containing dates with us (before finding the whale). 'Ubaida gave every person amongst us a handful of dates (and when the provision ran short), he then gave each one of us one date. And when that (stock) was exhausted, we felt its loss.
Sahih Al Bukhari: 5.287:
Narrated Ka`b bin Malik: I never failed to join Allah's Apostle in any of his Ghazawat except in the Ghazwa of Tabuk. However, I did not take part in the Ghazwa of Badr, but none who failed to take part in it, was blamed, for Allah's Apostle had gone out to meet the caravans of (Quraish, but Allah caused them (i.e. Muslims) to meet their enemy unexpectedly (with no previous intention) .
Sahih Al Bukhari: 5.702:
Narrated `Abdullah bin Ka`b bin Malik: Who, from among Ka`b's sons, was the guide of Ka`b when he became blind: I heard Ka`b bin Malik narrating the story of (the Ghazwa of) Tabuk in which he failed to take part. Ka`b said, "I did not remain behind Allah's Apostle in any Ghazwa that he fought except the Ghazwa of Tabuk, and I failed to take part in the Ghazwa of Badr, but Allah did not admonish anyone who had not participated in it, for in fact, Allah's Apostle had gone out in search of the caravan of Quraish till Allah made them (i.e. the Muslims) and their enemy meet without any appointment. I witnessed the night of Al−`Aqaba (pledge) with Allah's Apostle when we pledged for Islam, and I would not exchange it for the Badr battle although the Badr battle is more popular amongst the people than it (i.e. Al−`Aqaba pledge). As for my news (in this battle of Tabuk), I had never been stronger or wealthier than I was when I remained behind the Prophet in that Ghazwa. By Allah, never had I two she−camels before, but I had then at the time of this Ghazwa. Whenever Allah's Apostle wanted to make a Ghazwa, he used to hide his intention by apparently referring to different Ghazwa till it was the time of that Ghazwa (of Tabuk) which Allah's Apostle fought in severe heat, facing, a long journey, desert, and the great number of enemy.
Sahih Al Bukhari: 7.402:
Narrated Jabir: The Prophet sent us as an army unit of three hundred warriors under the command of Abu 'Ubaida to ambush a caravan of the Quraish. But we were struck with such severe hunger that we ate the Khabt (desert bushes), so our army was called the Army of the Khabt. Then the sea threw a huge fish called Al−`Anbar and we ate of it for half a month and rubbed our bodies with its fat till our bodies became healthy. Then Abu Ubaida took one of its ribs and fixed it over the ground and a rider passed underneath it. There was a man amongst us who slaughtered three camels when hunger became severe, and he slaughtered three more, but after that Abu 'Ubaida forbade him to do so.
