Quran 20:131 Taha, ayah 131 of 135

وَلَا تَمُدَّنَّ عَيْنَيْكَ إِلَىٰ مَا مَتَّعْنَا بِهِۦٓ أَزْوَٰجًا مِّنْهُمْ زَهْرَةَ ٱلْحَيَوٰةِ ٱلدُّنْيَا لِنَفْتِنَهُمْ فِيهِ ۚ وَرِزْقُ رَبِّكَ خَيْرٌ وَأَبْقَىٰ ۝١٣١

20:131 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.
