﴿ فَلَا تُعْجِبْكَ أَمْوَٰلُهُمْ وَلَآ أَوْلَٰدُهُمْ ۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُعَذِّبَهُم بِهَا فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَتَزْهَقَ أَنفُسُهُمْ وَهُمْ كَٰفِرُونَ ﴾

“Let not, then, their worldly goods or [the happiness which they may derive from] their children excite thy admiration: God but wants to chastise them by these means in this worldly life, and [to cause] their souls to depart while they are [still] denying the truth.”

So do not let their wealth or their children please you that is do not deem fair Our graces to them for this is a way of drawing them on by degrees to punish them God only desires thereby to chastise them in the life of this world by way of the hardship that they encounter in amassing such wealth and children and the calamities they suffer as a result thereof; and that their souls should depart while they are disbelievers so He punishes them in the Hereafter with the worst punishment.
