Sahih al-Bukhari Hadith 5494

The Prophet (ﷺ) sent us as an army unit of three hundred warriors under the command of Abu 'Ubaida رضی اللہ عنہ 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 رضی اللہ عنہ 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 رضی اللہ عنہ forbade him to do so.
