وَٱضْرِبْ لَهُم مَّثَلَ ٱلْحَيَوٰةِ ٱلدُّنْيَا كَمَآءٍ أَنزَلْنَٰهُ مِنَ ٱلسَّمَآءِ فَٱخْتَلَطَ بِهِۦ نَبَاتُ ٱلْأَرْضِ فَأَصْبَحَ هَشِيمًۭا تَذْرُوهُ ٱلرِّيَٰحُ ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ مُّقْتَدِرًا
And coin for them the similitude of the life of the world as water which We send down from the sky, and the vegetation of the earth mingleth with it and then becometh dry twigs that the winds scatter. Allah is able to do all things.
