H’adees’ Al-Quddsee

Fasting is Mine and it I who give reward for it. [A man] gives up his sexual passion, his food and his drink for my sake.Fasting is like a shield, and he who fasts has two joys: a joy when he breaks his fast and a joy when he meets his Lord. The change in the breath of the mouth of him who fasts is better in Allah’s estimation than the smell of musk.
