Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? 30 And We set in the earth firm mountains lest it should shake with them, and We set in it ravines to serve as ways, that haply so they may be guided; 31 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 And He it is Who has created the night and the day, and the sun and the moon, each in an orbit floating. 33 We made no mortal before you immortal. Will they become immortal after you die? 34 Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned. 35 And when those who disbelieve behold thee they only take thee up for mockery: is this he who mentioneth your gods? while in the mention of the compassionate they are themselves blasphemers. 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 37 They say: 'If you are truthful, when will this promise come' 38 If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them! 39 Nay, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved. 40 Mocked were (many) messenger before thee; But their scoffers were hemmed in by the thing that they mocked. 41
