The reward of giving

مَّثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنبُلَةٍ مِّائَةُ حَبَّةٍ ۗ وَاللَّهُ يُضَاعِفُ لِمَن يَشَاءُ ۗ وَاللَّهُ وَاسِعٌ عَلِيمٌ

سورة البقرة — الآية ٢٦١

“The example of those who spend their wealth in the cause of Allah is that of a grain that sprouts seven ears, with one hundred grains in every ear. And Allah multiplies the reward for whoever He wills.”
