Abu Hurairah reported,

The Messenger of Allah ﷺ said, "Whoever gives in charity the equivalent of a single date earned from lawful earnings, and Allah accepts only what is lawful, Allah accepts it with His right hand and then nurtures it for the giver as one of you nurtures his colt, until it becomes like a mountain."

Sahih

عن أبي هريرة، قال

قال رسول الله ﷺ: من تصدق بعدل تمرة من كسب طيب- ولا يقبل الله إلا الطيب- فإن الله يتقبلها بيمينه ثم يربيها لصاحبه كما يربي أحدكم فلوه حتى تكون مثل الجبل.
