This hadith has been narrated on the authority of Ibn 'Abbas (RA) from the Apostle of Allah ( صلی اللہ علیہ وسلم ) .

Ibn Abbas (RA) reported: A woman came to the Messenger of Allah ( صلی اللہ علیہ وسلم ) and said: Messenger of Allah, my mother has died and there is due from her a fast of vow; should I fast on her behalf? Thereupon he said: You see that if your mother had died in debt, would it not have been paid on her behalf? She said: Yes. He (the Holy Prophet) said: Then observe fast on behalf of your mother.

Abdullah bin Buraida (RA) reported on the authority of his father: When we were sitting with the Messenger of Allah ( صلی اللہ علیہ وسلم ) , a woman came to him and said: I had gifted to my mother a maid-servant, and now she (the mother) has died. Thereupon he (the Holy Prophet) said: There is a definite reward for you and she (the maid-servant) has been returned to you as an inheritance. She (that woman) again said: Fasts of a month (of Ramadan) are due upon her; should I observe them on her behalf? He (the Holy Prophet) said: Observe fasts on her behalf. She (again) said: She did not perform Hajj, should I perform it on her behalf? He (the Holy Prophet) said: Perform Hajj on her behalf.

'Abdullah bin Buraida (RA) reported on the authority of his father: I was sitting with the Apostle of Allah ( صلی اللہ علیہ وسلم ) ; the rest of the hadith is the same but with this variation that the (the narrator) said: "Fasts of two months."

Ibn Buraida (RA) reported on the authority of his father: A woman came to the Apostle of Allah ( صلی اللہ علیہ وسلم ) , and the rest of the hadith is the same, but he said: "Fasting of one month."

This hadith has been narrated on the authority of Sufyan with the same chain of transmitters in which it is said: "Fasting of two months."

Buraida (RA) reported a similar hadith on the authority of his father that a woman came to the Apostle of Allah ( صلی اللہ علیہ وسلم ) and he said: "Fasting for one month."

Abu Hurairah (RA) reported Allah's Apostle ( صلی اللہ علیہ وسلم ) as saying: If any one of you is invited to a meal when he is fasting, he should say: "I am fasting."

Abu Hurairah (RA) reported: When any one of you gets up in the morning in the state of fasting, he should neither use obscene language nor do any act of ignorance. And if anyone slanders him or quarrels with him, he should say: "I am fasting, I am fasting."

Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Allah, the Majestic and the Exalted, said: Every act of the son of Adam ؑؑis for him except fasting. It is done for My sake, and I will give a reward for it. By Allah in Whose Hand is the life of Muhammad, the breath of the observer of fast is sweeter to Allah than the fragrance of musk.
