Abu Hurairah reported,

The Messenger of Allah ﷺ said, "Whoever gives in charity the equivalent of a date from honest earnings, and nothing ascends to Allah except what is pure, Allah accepts it with His right hand, then nurtures it for its giver as one of you nurtures his foal, until it becomes like a mountain."

Sahih

عن أبي هريرة قال

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