At-Taghabun 64:18

إِنَّمَا أَمْوَالُكُمْ وَأَوْلَادُكُمْ فِتْنَةٌ ۚ وَاللَّهُ عِندَهُ أَجْرٌ عَظِيمٌ

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

فَاتَّقُوا اللَّهَ مَا اسْتَطَعْتُمْ وَاسْمَعُوا وَأَطِيعُوا وَأَنفِقُوا خَيْرًا لِّأَنفُسِكُمْ ۗ وَمَن يُوقَ شُحَّ نَفْسِهِ فَأُولَـٰئِكَ هُمُ الْمُفْلِحُونَ

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.

إِن تُقْرِضُوا اللَّهَ قَرْضًا حَسَنًا يُضَاعِفْهُ لَكُمْ وَيَغْفِرْ لَكُمْ ۚ وَاللَّهُ شَكُورٌ حَلِيمٌ

If you loan Allah a goodly loan, He will multiply it for you and forgive you. And Allah is Most Appreciative and Forbearing.
