Strain not thine eyes. (Wistfully) at what We have bestowed on certain classes of them, nor grieve over them: but lower thy wing (in gentleness) to the believers.[15:88]
Nor strain thine eyes in longing for the things We have given for enjoyment to parties of them, the splendour of the life of this world, through which We test them: but the provision of thy Lord is better and more enduring. [20:131]
Is it they who would portion out the Mercy of thy Lord? It is We Who portion out between them their livelihood in the life of this world: and We raise some of them above others in ranks, so that some may command work from others. But the Mercy of thy Lord is better than the (wealth) which they amass.
And were it not that (all) men might become of one (evil) way of life, We would provide, for everyone that blasphemes against (Allah) Most Gracious, silver roofs for their houses and (silver) stair-ways on which to go up,
And (silver) doors to their houses, and thrones (of silver) on which they could recline,
And also adornments of gold. But all this were nothing but conveniences of the present life: The Hereafter, in the sight of thy Lord is for the Righteous. [43:32-35]
