Beautiful Hadith is about Fasting

On the authority of Abu Hurayrah RA from the Prophet (peace be upon him), who said: Allah (mighty and sublime be He) says: Fasting is Mine and it is 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. It was related by al-Bukhari (also by Muslim, Malik, at-Tirmidhi, an-Nasa'i and Ibn Majah). - Hadith Qudsi 10
