what is the rewarding for giving alms?

1. Who is he that will loan to Allah a beautiful loan, which Allah will double unto his credit and multiply many times? It is Allah that gives (you) Want or plenty, and to Him shall be your return.

2. The metaphor of those who spend their wealth in the Way of Allah is that of a grain which produces seven ears; in every ear there are a hundred grains. Allah gives such multiplied increase to whoever He wills. Allah is All-Encompassing, All-Knowing.

3. The metaphor of those who spend their wealth, desiring the pleasure of Allah and firmness for themselves, is that of a garden on a hillside. When heavy rain falls on it, it doubles its produce; and if heavy rain does not fall, there is dew. Allah sees what you do.
