The provision of thy Lord is better and more enduring...

أَفَلَمْ يَهْدِ لَهُمْ كَمْ أَهْلَكْنَا قَبْلَهُم مِّنَ الْقُرُونِ يَمْشُونَ فِي مَسَاكِنِهِمْ ۗ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِّأُولِي النُّهَىٰ  

وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَكَانَ لِزَامًا وَأَجَلٌ مُّسَمًّى

فَاصْبِرْ عَلَىٰ مَا يَقُولُونَ وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا ۖ وَمِنْ آنَاءِ اللَّيْلِ فَسَبِّحْ وَأَطْرَافَ النَّهَارِ لَعَلَّكَ تَرْضَىٰ  

وَلَا تَمُدَّنَّ عَيْنَيْكَ إِلَىٰ مَا مَتَّعْنَا بِهِ أَزْوَاجًا مِّنْهُمْ زَهْرَةَ الْحَيَاةِ الدُّنْيَا لِنَفْتِنَهُمْ فِيهِ ۚ وَرِزْقُ رَبِّكَ خَيْرٌ وَأَبْقَىٰ

Is it not a warning to such men (to call to mind) how many generations before them We destroyed, in whose haunts they (now) move? Verily, in this are Signs for men endued with understanding.

Had it not been for a Word that went forth before from thy Lord, (their punishment) must necessarily have come; but there is a Term appointed (for respite).

Therefore be patient with what they say, and celebrate (constantly) the praises of thy Lord, before the rising of the sun, and before its setting; yea, celebrate them for part of the hours of the night, and at the sides of the day: that thou mayest have (spiritual) joy.

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.

Surah Ta-Ha [20:128-131]
