Sahih Muslim, 2342

Rapporté par Abu Huraira رضي الله عنه : Le Messager d’Allah ﷺ a dit : « Si quelqu’un donne en aumône ne serait-ce qu’une datte provenant d’un gain licite — car Allah n’accepte que ce qui est licite — Allah la prend de Sa main droite, et même si ce n’est qu’une datte, Allah la fait fructifier dans Sa main, comme l’un de vous élève un poulain, jusqu’à ce qu’elle devienne plus grande qu’une montagne. »

Abu Huraira reported Allah's Messenger (ﷺ) as saying:If anyone gives as Sadaqa the equivalent of a date from that (earning) earned honestly, for Allah accepts that which is lawful, the Lord would accept it with His Right Hand, and even if it is a date, it would foster in the Hand of the lord, as one of you fosters his colt, till it becomes bigger than a mountain
