إِنَّمَآ أَمْوَٰلُكُمْ وَأَوْلَـٰدُكُمْ فِتْنَةٌ ۚ وَٱللَّهُ عِندَهُۥٓ أَجْرٌ عَظِيمٌ
Your wealth and your children are but a trial, and Allah has with Him a great reward.
فَٱتَّقُوا۟ ٱللَّهَ مَا ٱسْتَطَعْتُمْ وَٱسْمَعُوا۟ وَأَطِيعُوا۟ وَأَنفِقُوا۟ خَيْرًا لِّأَنفُسِكُمْ ۗ وَمَن يُوقَ شُحَّ نَفْسِهِۦ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
So fear Allah as much as you are able and listen and obey and spend [in the way of Allah]; it is better for your selves. And whoever is protected from the stinginess of his soul - it is those who will be the successful.
