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 And when a wave covereth them like awnings, they call upon Allah, making their religion pure for Him. Then when He delivereth them on the land, only some of them keep to the middle course. And none gainsaith Our signs save each perfidious, ingrate one. 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 Verily Allah! with Him alone is the knowledge of the Hour, and He it is who sendeth down the rain and knoweth that which is in the wombs: and no person knoweth whatsoever it shall earn on the morrow, and a person knoweth not in whatsoever land he shall die. Verily Allah is Knowing, Aware. 34
