Abu Huraira reported Allah’s Messenger (may peace be upon him) 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.

Narrated Abu Huraira:

I heard Allah’s Apostle saying regarding Ramadan, “Whoever prayed at night in it (the month of Ramadan) out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven.”
