Observest thou not that the ship saileth in the sea by the favour of Allah that he may shew you of His signs? Verily therein are signs for every persevering, grateful heart. 31 When the waves cover them like shadows, they pray to God with sincerity in their religion, but when We bring them safely to land, only some of them follow the right path. No one rejects Our revelations except the treacherous ungrateful ones. 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 Allah alone has the knowledge of the Hour. It is He Who sends down the rain and knows what is in the wombs, although no person knows what he will earn tomorrow, nor does he know in which land he will die. Indeed, Allah is All-Knowing, All-Aware. 34
