The Messenger of Allah ﷺ said, "No one gives charity from what is wholesome, and Allah accepts only what is wholesome, but the Most Merciful
takes it in His right hand. Even if it is a single date, it grows in the palm of the Most Merciful until it becomes greater than a mountain, just as one of you raises his foal or young camel."

قال رسول الله ﷺ ما تصدق أحد بصدقة من طيب ولا يقبل الله عز وجل إلا الطيب إلا أخذها الرحمن عز وجل بيمينه وإن كانت تمرة فتربو في كف الرحمن حتى تكون أعظم من الجبل كما يربي أحدكم فلوه أو فصيله
