And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders. 16 And We guard it against every accursed Shaitan, 17 Save him who stealeth the hearing, and them doth a clear flame pursue. 18 And the earth -- We stretched it forth, and cast on it firm mountains, and We caused to grow therein of every thing justly weighed, 19 and there appointed for you livelihood, and for those you provide not for. 20 And there is not a thing, but with Us are the stores thereof. And We send it not down except in a known measure. 21 And We send the winds fertilising, and cause water to descend from the sky, and give it you to drink. It is not ye who are the holders of the store thereof. 22 for, behold, it is We - We alone - who grant life and deal death, and it is We alone who shall remain after all else will have passed away! 23 And well do We know [the hearts and deeds of all human beings - both] those who lived before you and those who will come after you; 24 and, behold, it is thy Sustainer who will gather them all together [on Judgment Day]: verily, He is Wise, All-Knowing! 25
