Do you not see how the ships run upon the sea, by the Favor of Allah so that He may show you His signs? Surely, there are signs in this for every steadfast, thankful person. 31 And when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one. 32 O MEN! Be conscious of your Sustainer, and stand in awe of the Day on which no parent will be of any avail to his child, nor a child will in the least avail his parent! Verily, God's promise [of resurrection] is true indeed: let not, then, the life of this world delude you, and let not [your own] deceptive thoughts about God delude you! 33 Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware. 34
