مَثَلُ الَّذِينَ يُنفِقُونَ اَموَالَهُم فِى سَبِيلِ اللّٰهِ كَمَثَلِ حَبَّةٍ اَنبَتَت سَبعَ سَنَابِلَ فِى كُلِّ سُنبُلَةٍ مِّائَةُ حَبَّةٍ‌ؕ وَاللّٰهُ يُضٰعِفُ لِمَن يَّشَآءُ‌ ؕ وَاللّٰهُ وَاسِعٌ عَلِيمٌ﴿۲۶۱﴾‏

The example of those who spend their wealth in the way of Allah is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allah multiplies [His reward] for whom He wills. And Allah is all-Encompassing and Knowing. (Al-Quran, 261)
