A grain to hundreds!!

in Quran (2:261) Allah says:
The likeness of those who spend their wealth in Allah’s way is as the likeness of a grain which groweth seven ears, in every ear a hundred grains. Allah giveth increase manifold to whom He will. Allah is All-Embracing, All-Knowing.

and the prophet Muhammad said
"If the Final Hour comes while you have a palm-cutting in your hands and it is possible to plant it before the Hour comes, you should plant it."
