Jabir b. Abdullah reported that Allah's Messenger (may peace be upon him) sent an expedition to the sea coast and I was one among them. The rest of the hadith is the same with a slight variation of wording that in the hadith transmitted on the authority of Wahb b. Kaisan (the words are):" The army ate out of that (the whale) for eighteen days."
