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 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 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 Only God has the knowledge of the coming of the Hour of Doom. He sends down the rain and knows what is in the wombs. No soul is aware of what it will achieve tomorrow and no soul knows in which land it will die. God is All-knowing and All-aware. 34
