He it is Who enables you to journey through the land and on the sea. When you are on the ships, and these (means of transport) with those (on board) sail with a fair breeze, while they are taking a joyful pride in them, a violent wind overtakes them, wave (after wave) surges on them from every side, and they feel sure that they are caught in a disaster, (then) they call upon Allâh with a sincere faith in Him (saying), `If You deliver us from this (calamity) we will certainly be of the thankful.'
