Verse 261

مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍ مِّا۟ئَةُ حَبَّةٍ وَٱللَّهُ يُضَـٰعِفُ لِمَن يَشَآءُ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ

An example of those who spend their money in the cause of God is like the example of a seed that grows seven clusters, in each cluster there are one hundred seeds. God thus multiplies for whomever He wills. And God is Expander, All Knowing.
