Among Allah's blessings for humanity

It is your Lord who drives your ships across the seas that you may seek of His bounty. He is verily kind to you.

When a calamity befalls you on the sea, all those you invoke fail you except Him. But when He brings you safely to the shore, you turn away, for man is most ungrateful.

Have you then become so sure that He will not cleave the earth and sink you in it by the shore, or send a gale against you, when you will not find any protector.

Or you feel so secure that He will not send you back (to sea) again or send a gravel-hurtling storm against you, and drown you for your ingratitude? Then you will not find any avenger against Us.

Indeed We have honoured the children of Adam, and carried them over land and sea, provided them with good things for their sustenance, and exalted them over many of Our creatures.
