عن أبي هريرة رضي الله عنه قال قال رسول الله صلى الله عليه وسلم من تصدق بعدل تمرة من كسب طيب ولا يقبل الله إلا الطيب وإن الله يتقبلها بيمينه ثم يربيها لصاحبه كما يربي أحدكم فلوه حتى تكون مثل الجبل (صحيح بخاري #1410)

Hazrat Abu Hurairah (radhiyallahu ‘anhu) narrates that Rasululah (sallallahu ‘alaihi wasallam) said, “Whoever gives sadaqah (charity) equal to a date from pure wealth – and Allah only accepts that which is pure – then Allah accepts it with His right hand, and thereafter protects it (and allows it to grow) for the one who gave it, just as one of you nurtures and takes care of his young foal (until it grows up into a fully developed horse), until his charity becomes like a mountain.”

Note: Allah Ta‘ala is unique in His being and His attributes and there is nothing that can be compared to Him. Allah Ta‘ala does not have a body and limbs as the creation has. However, in this Hadith, ‘right hand of Allah’ is mentioned. Generally, when something is appreciated and valued, it is received with the right hand. Hence, the ‘right hand of Allah Ta‘ala’ mentioned in this Hadith is in actual fact an expression to show the appreciation and value with which Allah Ta‘ala accepts this charity.
