LILLAH

Allah says in the Qur’an, Surah Al-Baqarah (2:261):

مَثَلُ الَّذِينَ يُنْفِقُونَ أَمْوَالَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنْبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنْبُلَةٍ مِائَةُ حَبَّةٍ ۗ وَاللَّهُ يُضَاعِفُ لِمَنْ يَشَاءُ ۗ وَاللَّهُ وَاسِعٌ عَلِيمٌ

The example of those who spend their wealth in the path of Allah is like a seed that grows seven ears; in every ear are one hundred grains. And Allah multiplies for whom He wills. And Allah is All-Encompassing, All-Knowing.

This shows that one sincere act of giving can be rewarded seven hundred times or more by Allah.
