He it is who enableth you to travel by land and sea until when ye are in ships and they run away with them with a goodly wind and they rejoice thereat, there cometh upon them a tempestuous wind and there cometh unto them a billow from every side, and they imagine that they are encompassed therein, they cry unto Allah making there faith pure for Him: If Thou deliverest us from this. we would surely be of those who are thankful.
