Quran 2:261 from Surah Al-Baqara on Divine Marvels.
مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمۡوَٰلَهُمۡ فِي سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتۡ سَبۡعَ سَنَابِلَ فِي كُلِّ سُنۢبُلَةٖ مِّاْئَةُ حَبَّةٖۗ وَٱللَّهُ يُضَٰعِفُ لِمَن يَشَآءُۚ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ
English translation: Example (of) those who spend their wealth in (the) way (of) Allah (is) like a grain which grows seven ears in each ear hundred grain(s) And Allah gives manifold to whom He wills And Allah (is) All-Encompassing All-Knowing
Transliteration: mathalu alladhina yunfiquna amwalahum fi sabili al-lahi kamathali habbatin anbatat sab'a sanabila fi kulli sunbulatin mi-atu habbatin wal-lahu yuda'ifu liman yashau wal-lahu wasi'un alimun
