Seest thou not that the ships sail through the ocean by the Grace of Allah?- that He may show you of His Signs? Verily in this are Signs for all who constantly persevere and give thanks. 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 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
