He is the One who enables you to travel on land and at sea, until when you are in the boats and they sail with those on board under a good wind and they are pleased with it, there comes upon them a violent wind, and the wave comes upon them from many sides. And (when) they think that they are encircled, they pray to Allah, having faith in Him alone, (and say,) "If You deliver us from this, we shall be grateful indeed."
