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 if a wave enshroudeth them like awnings, they cry unto Allah, making their faith pure for Him only. But when He bringeth them safe to land, some of them compromise. None denieth Our signs save every traitor ingrate. 32 O mankind! Be afraid of your Lord (by keeping your duty to Him and avoiding all evil), and fear a Day when no father can avail aught for his son, nor a son avail aught for his father. Verily, the Promise of Allah is true, let not then this (worldly) present life deceive you, nor let the chief deceiver (Satan) deceive you about Allah. 33 Surely God -- He has knowledge of the Hour; He sends down the rain; He knows what is in the wombs. No soul knows what it shall earn tomorrow, and no soul knows in what land it shall die. Surely God is All-knowing, All-aware. 34
