Have you not seen how the ships sail on the sea by God's grace so that He may show you some of His signs? Surely therein are signs for every steadfast, thankful person. 31 When the waves engulf them like shadows [of death], they call to God, sincere [at that moment] in their faith in Him alone: but as soon as He has brought them safe ashore, only some of them take the right course. And none denies Our signs save the perfidious and ungrateful person. 32 O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver. 33 Indeed, Allah [alone] has knowledge of the Hour and sends down the rain and knows what is in the wombs. And no soul perceives what it will earn tomorrow, and no soul perceives in what land it will die. Indeed, Allah is Knowing and Acquainted. 34
