Abu Hurairah reported,
The Messenger of Allah ﷺ said, "Whoever gives in charity the equivalent of a date from lawful earnings, and nothing ascends to Allah except what is pure, Allah will accept it with His right hand, then nurture it for its owner the way one of you raises his foal, until it becomes like a mountain."
Azami 259
Sahihعن أبي هريرة، قال
قال رسول الله ﷺ: من تصدق بعدل تمرة من كشب طيب، ولا يصعد إلى الله إلا الطيب؛ فإن الله يتقبله بيمينه، ثم يربيها لصاحبه كما يربي أحدكم فلوه حتى تكون مثل الجبل.
