Surah Al-Anfal 8:28

وَٱعْلَمُوٓا۟ أَنَّمَآ أَمْوَٰلُكُمْ وَأَوْلَـٰدُكُمْ فِتْنَةٌ وَأَنَّ ٱللَّهَ عِندَهُۥٓ أَجْرٌ عَظِيمٌ

And know that your properties and your children are but a trial and that Allāh has with Him a great reward.

Translation: Saheeh International

Tafsir

And know that your wealth and your children are a trial for you impeding you from the concerns of the Hereafter; and that with God is a tremendous wage so do not forfeit it by giving undue attention to wealth and children acting treacherously for the sake of preserving them.
