Rewards for fasting
Answer:
In the name of Allah, the most Beneficent, the most Merciful.
Saaiduna Abu Saeed Khudri 
narrates that the Prophet of Allah 
said: “When a servant of Allah observes the fast for a day for the sake of Allah, He thereby repels the Fire from him a distance of seventy years journeying”. (Sahih Bukhari)
The Prophet of Allah has said: “There is not a believer who remains hungry and abstains from the forbidden things, and does not wrongfully consume the wealth of Muslims, except that Allah will feed him from the fruits of Heaven”. (Musnad Abi Hanifah)
