Abu Huraira, may Allah be pleased with him, reported Allah's Messenger, may the peace and blessings of Allah be upon him, said: Allah the Exalted and Majestic said: Every act of the son of Adam is for him, except fasting. It is (exclusively) meant for Me and I (alone) will reward it. Fasting is a shield. When any one of you is fasting on a day, he should neither indulge in obscene talk, nor raise his voice, yet, if anyone reviles him or tries to quarrel with him he should say: I am a fasting person. By Him, in Whose Hand is the life of Muhammad, the breath of the fasting person is dearer to Allah on the Day of judgment than the fragrance of musk. The one who fasts has two (occasions) of joy, one when he breaks his fasting; he is glad with the breaking of (the fast) and one when he meets his Lord he is glad with his fast.
