'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.

'A'isha, the Mother of the Believers (Allah be pleased with her), reported: The Apostle of Allah ( صلی اللہ علیہ وسلم ) came to me one day and said: Is there anything with you (to eat)? I said: No. Thereupon he said: I shall then be fasting. Then he came to us another day and we said: Messenger of Allah, has been offered to us as a gift. Thereupon he said: Show that to me; I had been fasting since morning. He then ate it.
