Al-Baqarah 2:261
مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍ مِّا۟ئَةُ حَبَّةٍ ۗ وَٱللَّهُ يُضَـٰعِفُ لِمَن يَشَآءُ ۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ

"The example of those who spend their wealth in the way of Allāh is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allāh multiplies [His reward] for whom He wills. And Allāh is all-Encompassing and Knowing."
Al-Baqarah 2:261, translation by Sahih International
A short reflection
The likeness of those who spend in the path of Allah is a seed that grows seven ears, in each hundred grains.
