Quote From The Holy Quran

The charity of those who expend their wealth in the Way of Allah may be likened to a grain of corn, which produces seven ears and each ear yields a hundred grains. Likewise Allah develops manifold the charity of anyone He pleases, for He is All-Embracing, All-Wise.

Hadith

Narrated by Abu Huraira

A man asked the Prophet (saws), “O Allah’s Messenger (saws)! What kind of charity is the best?” He (saws) replied. “To give in charity when you are healthy and greedy hoping to be wealthy and afraid of becoming poor. Don’t delay giving in charity till the time when you are on the death bed when you say, ‘Give so much to so-and-so and so much to so-and so,’ as at that time the property is not yours but it belongs to so-and-so (i.e. your inheritors).”
