The Forty Hadith Qudsi Abu Hurayrah Sahih On the authority of Abu Hurayrah (may Allah be pleased with him) from the Prophet (ﷺ), 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. https://parallelquran.com/hadith/forty-qudsi-10/
