It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent an army towards the seashore, and appointed Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) as their commander. There were three hundred men in this army, and I was among them. On the way, the food ran out. Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) ordered that whatever food remained should be gathered together. When it was all collected, it amounted to two containers of dates. Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) would give us a little food from it each day, until it came to the point that only one date would be our share. Then even that finished. Wahb bin Kaysan says: I asked Sayyiduna Jabir (may Allah be pleased with him): What would you do with one date each? He said: When even that was gone, then we realized its value. When we reached the seashore, we found a fish lying there, as large as a mountain. The entire army ate from it for eighteen days and nights. Then Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) ordered that the bones of the fish be set upright. Two bones were set upright, and a camel passed underneath them without touching them.

Imam Malik (may Allah have mercy on him) says (the word of the hadith) «الظَّرِبُ» refers to a small mountain.
