Selected Sayings of The Holy Prophet of Islam — Page 24
Fasting 31. Abu Hurairah, God be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said: "Allah The Almighty says that all the deeds of a man are for his own sake except the fast. 'The fast is kept for My sake alone, and I am the reward for it. ' The fast is a shield against evil. Thus, when anyone of you is fasting, he should neither indulge in idle talk nor raise his voice. If anyone abuses him or starts quarreling with him, he should just say, 'I am fasting. ' Let Allah the Possessor of Muhammad and his life bear me out: the breath of one who is fasting is purer in the sight of Allah than the fragrance of musk. One who fasts experiences two joys: he is joyful when he breaks the fast, and he is joyful by virtue of the fast when he meets his Lord. " (Bukhari) 24
