He it is Who makes you travel by land and sea; until, when you are in the ships, and they sail on with them in a pleasant breeze, and they rejoice at it, a violent wind overtakes them and the billows surge in on them from all sides, and they deem that they are encompassed about. Then they pray to Allah, being sincere to Him in obedience: If Thou deliver us from this, we will certainly be of the grateful ones.
