Surah Al-Baqarah, Verse 261

مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمۡوَٰلَهُمۡ فِي سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتۡ سَبۡعَ سَنَابِلَ فِي كُلِّ سُنۢبُلَةٖ مِّاْئَةُ حَبَّةٖۗ وَٱللَّهُ يُضَٰعِفُ لِمَن يَشَآءُۚ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ٢٦١

mathalu alladhīna yunfiqūna amwālahum fī sabīli l-lahi kamathali ḥabbatin anbatat sabʿa sanābila fī kulli sunbulatin mi-atu ḥabbatin wal-lahu yuḍāʿifu liman yashāu wal-lahu wāsiʿun ʿalīmun

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.
