Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Fasting is a shield.

Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: 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 language, nor raise the voice; or if anyone reviles him or tries to quarrel with him he should say: I am a person fasting. By Him, in Whose Hand is the life of Muhammad, the breath of the observer of fast is sweeter 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 the fast he is glad with the breaking of (the fast) and one when he meets his Lord he is glad with his fast.

Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Every (good) deed of the son of Adam ؑؑwould be multiplied, a good deed receiving a tenfold to seven hundredfold reward. Allah, the Exalted and Majestic, has said: With the exception of fasting, for it is done for Me and I will give a reward for it, for one abandons his passion and food for My sake. There are two occasions of joy for one who fasts, joy when he breaks it, and joy when he meets his Lord, and the breath (of an observer of fast) is sweeter to Allah than the fragrance of musk.

A hadith like this is narrated on the authority of Abu Sinan with the same chain of transmitters (and the words are): "As he meets Allah, He rewards him, and he is happy."

Sahl bin Sa'd (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: In Paradise there is a gate which is called Rayyan through which only the observers of fast would enter on the Day on Resurrection. None else would enter along with them. It would be proclaimed: Where are the observers of fast that they should be admitted into it? -and when the last of them would enter, it would be closed and no one would enter it.

Abu Sa'id al Khudri (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Every servant of Allah who observes fast for a day in the way of Allah, Allah would remove, because of this day, his face farther from the Fire (of Hell) to the extent of seventy years' distance.

This hadith has been narrated by Suhail with the same chain of transmitters.

Abu Sa'id al-Khudri (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: He who observes fast for a day in the way of Allah He would remove his face from the Hell to the extent of seventy years' distance.

'A'isha, the Mother of the Believers (Allah be pleased with her), reported that one day the Messenger of Allah ( صلی اللہ علیہ وسلم ) said to me: 'A'isha, have you anything (to eat)? I said: 'Messenger of Allah, there is nothing with us. Thereupon he said: I am observing fast. She said: The Messenger of Allah ( صلی اللہ علیہ وسلم ) went out, and there was a present, for us and (at the same time) some visitors dropped in. When the Messenger of Allah ( صلی اللہ علیہ وسلم ) came back, I said to him: Messenger of Allah, a present was given to us, (and in the meanwhile) there came to us visitors (a major Portion of it has been spent on them), but I have saved something for you. He said: What is it? I said: It is hasees (a compound of dates and clarified butter). He said: Bring that. So I brought it to him and he ate it and then said: I woke up in the morning observing fast. Talha said: I narrated this hadith to Mujahid and he said: This (observing of voluntary fast) is like a person who sets apart Sadaqa out of his wealth. He may spend it if he likes, or he may retain it if he so likes.
