إِنَّمَآ أَمْوَٰلُكُمْ وَأَوْلَـٰدُكُمْ فِتْنَةٌ ۚ وَٱللَّهُ عِندَهُۥٓ أَجْرٌ عَظِيمٌ

Your wealth and your children are but a trial, and Allāh has with Him a great reward.

Translation: Saheeh International

Tafsir

Your possessions and your children are only a trial for you distracting you from the concerns of the Hereafter and God — with Him is a great reward so do not forfeit it by preoccupying yourselves with possessions and children.
