See you not that the ships sail through the sea by Allah's Grace? that He may show you of His Signs? Verily, in this are signs for every patient, grateful (person). 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 people, fear your Lord and dread the day when no father will avail a son, nor son his father. Truly the promise of God is true. Do not be deluded by the life of this world, and do not let the deceiver draw you away from God. 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
