And in no wise covet those things in which God Hath bestowed His gifts More freely on some of you than on others: To men is allotted what they earn, and to women what they earn: But ask God of His bounty. For God hath full knowledge of all things. (4:32)

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)

God commands justice, the doing of good, and liberality to kith and kin, and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that ye may receive admonition. (16:90)

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)
