Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And We have made from water every living thing. Will they not then believe? 30 And We have placed in the earth firm hills lest it quake with them, and We have placed therein ravines as roads that haply they may find their way. 31 And We made the sky a well-protected roof. Still they turn away from His signs! 32 It is He Who created the night and the day, and the sun and the moon. Each of them is floating in its orbit. 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 34 Every living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to return. 35 And when those who disbelieve (in the Oneness of Allah) see you (O Muhammad SAW), they take you not except for mockery (saying): "Is this the one who talks (badly) about your gods?" While they disbelieve at the mention of the Most Beneficent (Allah). [Tafsir. Al-Qurtubi]. 36 Man has been created hasty; very soon I shall show you My signs, do not be impatient. 37 But they [who reject My messages are wont to] ask, "When is that promise [of God's judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 38 If they but knew - they who are bent on denying the truth - [that there will come] a time when they will not be able to ward off the fire from their faces, nor from their backs, and will not find any succour! 39 Nay, but it shall come upon them suddenly, dumbfounding them, and they shall not be able to repel it, nor shall they be respited. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
