وَاضْرِبْ لَهُم مَّثَلَ الْحَيَاةِ الدُّنْيَا كَمَاءٍ أَنزَلْنَاهُ مِنَ السَّمَاءِ فَاخْتَلَطَ بِهِ نَبَاتُ الْأَرْضِ فَأَصْبَحَ هَشِيمًا تَذْرُوهُ الرِّيَاحُ ۗ وَكَانَ اللَّهُ عَلَىٰ كُلِّ شَيْءٍ مُّقْتَدِرًا (45)
(18:45) And O Prophet, bring home to them the reality of this worldly life by a parable. It is like the vegetation of the earth that flourished luxuriantly when We sent down rain water from the sky, but afterwards the same vegetation was turned into chaff, which is blown away by the wind: Allah has power over everything. *41
*41) "Allah has power over everything": He gives life and also death: He causes the rise and the downfall: It is by His conunand that the seasons change. Therefore, O disbelievers, if you are enjoying prosperity today, you should be under no delusion that this condition will remain for ever. That God, by Whose conunand these things have been bestowed on you, has the power to snatch away all this by another conunand.
