"" Commentary ...
Then there comes upon them a stormy wind and the waves come on them from all sides, and they think that they are encompassed therewith, they call upon Allah, making their faith pure for Him,(saying): 'If You deliver us from this, we shall surely be of the grateful ones'.
" Commentary : In this verse the Qur'an appeals to the depths of human nature, explaining to them the monotheism which is embedded in their very being, describing to them how man once in great difficulty and danger, tends to forget everything but Allah. First, He says that He is the One Who enables you to traverse through the land and the sea.
And, when you go on board a ship, He makes you eventually get, you and your ship, to your destination with the help of the appropriate winds that gladden every heart. Then when a horrible thunderstorm blows and waves buffet them from all sides, it makes them realize that death is near, and they lose their hopes of survival.
The verse says: " He it is Who enables you to traverse through land and sea; so that you are in the ships, and they sail with them with a favourable wind, and they rejoice thereat. Then there comes upon them a stormy wind and the waves come on them from all sides, and they think that they are encompassed therewith, ..." At just about that time, they are reminded of Allah and call upon Him sincerely, their thoughts stripped of all sorts of polytheism and idol worship.
The verse continues saying: "... they call upon Allah, making their faith pure for Him, ..." They start praying at this time, saying that if Allah save them from this plight, they will thank Him while they shall neither oppress others nor turn to others for help save Him. The verse says: "... (saying): 'If You deliver us from this, we shall surely be of the grateful ones'.
