And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders. 16 and have protected them against every accursed satan 17 But any that gains a hearing by stealth, is pursued by a flaming fire, bright (to see). 18 And the earth - We have spread it and cast therein firmly set mountains and caused to grow therein [something] of every well-balanced thing. 19 and there appointed for you livelihood, and for those you provide not for. 20 And there is not of aught but with Us are the treasures thereof, and We send it not down save in a measure known 21 And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance), though ye are not the guardians of its stores. 22 It is We who give life, and make to die, and it is We who are the inheritors. 23 We know those of you who press forward, and We know the laggards, 24 Assuredly it is thy Lord Who will gather them together: for He is perfect in Wisdom and Knowledge. 25
