Sura al-Baqara 2:261

مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّـهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍ مِّا۟ئَةُ حَبَّةٍ وَٱللَّـهُ يُضَٰعِفُ لِمَن يَشَآءُ وَٱللَّـهُ وَٰسِعٌ عَلِيمٌ

mathalu lladhīna yunfiqūna amwālahum fī sabīli allāhi ka-mathali ḥabbatin anbatat sabʿa sanābila fī kulli sunbulatin miatu ḥabbatin wallāhu yuḍāʿifu li-man yashāʾu wallāhu wāsiʿun ʿalīmun

The parable of those who spend their substance in the way of Allah is that of a grain of corn: it groweth seven ears, and each ear Hath a hundred grains. Allah giveth manifold increase to whom He pleaseth: And Allah careth for all and He knoweth all things.
