Narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever gives charity from lawful earnings, even if it is equal to a single date, and only lawful things ascend to Allah Almighty, then Allah Almighty accepts it with His right hand and continues to nurture it for its owner, just as one of you raises his foal, until that single date becomes equal to a mountain.
