On the authority ofAbu Harayah (May Allah be pleased with him) from the Prophet(Peace be upon him)
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 drink for My sake.
Fasting is like a SHEILD
And he who fasts has two joys. A joy of when he breaks his Fast and a JOY when he MEETS his Lord.
Narrated by al-Bukhari (also by Muslim, Malik, at-Tirmidhi, an-Nasa’i and Ibn Majah)
