And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders. 16 and We have made them secure against every satanic force accursed 17 Except him (devil) that gains hearing by stealing, he is pursued by a clear flaming fire. 18 And the earth - We have spread it out wide, and placed on it mountains firm, and caused [life] of every kind to grow on it in a balanced manner, 19 And We have provided therein means of subsistence,- for you and for those for whose sustenance ye are not responsible. 20 Naught is there, but its treasuries are with Us, and We send it not down but in a known measure. 21 And We have sent the fertilizing winds and sent down water from the sky and given you drink from it. And you are not its retainers. 22 And indeed, it is We who give life and cause death, and We are the Inheritor. 23 We surely know those of you who go forward and those of you who lag behind. 24 And surely your Lord will gather them together; surely He is Wise, Knowing. 25
