Ta-Ha - 20:131

وَلَا تَمُدَّنَّ عَيْنَيْكَ إِلَى مَا مَتَّعْنَا بِهِ أَزْوَاجًا مِّنْهُمْ زَهْرَةَ الْحَيَاةِ الدُّنيَا لِنَفْتِنَهُمْ فِيهِ وَرِزْقُ رَبِّكَ خَيْرٌ وَأَبْقَى
[20:131]
And do not stretch your eyes after that with which We have provided different classes of them, (of) the splendor of this world's life, that We may thereby try them; and the sustenance (given) by your Lord is better and more abiding.
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.
And strain not thine eyes toward that which We cause some wedded pairs among them to enjoy, the flower of the life of the world, that We may try them thereby. The provision of thy Lord is better and more lasting.
