Do you not see that ships sail in the sea by Allah's Grace that He may show you some of His Signs? Surely there are Signs in this for everyone who is steadfast, thankful. 31 And if a wave comes upon them like mountains, they pray to Allah believing purely in Him; then when He brings them safely to land, some of them remain upon justice; and none will deny Our signs except an extremely unfaithful, ungrateful person. 32 Mankind, have fear of your Lord and the day when a father will be of no avail to his son, nor will a son carry any part of the burden of his father. The promise of God is true. Do not let the worldly life deceive you nor let your pride deceive you about God. 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
