Translation of the verse 131 from Surah Ta-Ha : Number of verses 135 - - page 321 - Part 16.
And strain not your eyes in longing for the things We have given for enjoyment to various groups of them (polytheists and disbelievers in the Oneness of Allah), the splendour of the life of this world that We may test them thereby. But the provision (good reward in the Hereafter) of your Lord is better and more lasting.
And do not extend your eyes toward that by which We have given enjoyment to [some] categories of them, [its being but] the splendor of worldly life by which We test them. And the provision of your Lord is better and more enduring.
(20:131) And do not cast an envious look at the worldly property We have bestowed on different kinds of people, for We have given them all that to put them to trial, and the lawful provision *113 of your Lord is better and more lasting:
*113) It means: "It does not behove you and your companions to be envious of the riches of the wicked people who are amassing wealth by unlawful means. The best thing for you is the lawful provision which you earn by your hard labour, even though this may be meagre in quantity. That is better for the pious and righteous and is of everlasting virtue."
