Allah Subhanahu wa Ta'ala says (Qur'an Translation): And of His signs are the ships, like (floating) mountains in the sea; If He wills, He calms the wind so that they keep still upon its surface. Indeed, herein are signs for every patient and grateful (heart). Or (if He wills), He causes them to perish, on account of that which they have earned and He forgives much. (Ash-Shu'ra 42: 32-34)
