Quran 9:55 At-Tawbah, ayah 55 of 129

فَلَا تُعْجِبْكَ أَمْوَٰلُهُمْ وَلَآ أَوْلَـٰدُهُمْ ۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُعَذِّبَهُم بِهَا فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَتَزْهَقَ أَنفُسُهُمْ وَهُمْ كَـٰفِرُونَ ۝٥٥

9:55 So let not their riches nor their children please thee (O Muhammad). Allah thereby intendeth but to punish them in the life of the world and that their souls shall pass away while they are disbelievers.
