Hast thou not seen how the ships glide on the sea by Allah's grace, that He may show you of His wonders? Lo! therein indeed are portents for every steadfast, grateful (heart). 31 When the waves, like shadows, envelop them, they call to Allah making their religion sincerely His, but no sooner does He bring them safely to land then some of them are halfhearted. None denies Our verses, except the ungrateful traitor. 32 O mankind! Keep your duty to your Lord and fear a Day when the parent will not be able to avail the child in aught, nor the child to avail the parent. Lo! Allah's promise is the very truth. Let not the life of the world beguile you, nor let the deceiver beguile you, in regard to Allah. 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
