So ‘Abdur-Razzaaq asked about him, and was told he had not eaten anything for the last three days.
I saw the Messenger of Allaah (sal-Allaahu ‘alayhi wa sallam) in a dream last night, and he (sal-Allaahu ‘alayhi wa sallam) said [to me]…
Daawood ibn Abee Hind fasted for forty years, and his family were not aware of it. He was very discrete, and would take his [packed] lunch with him, and then give it away [to someone needy] along the way.
If you were not from my family I would not have told you this about my father; he was steadfast in fasting every other day for forty years, and he would [also] pray the fajr prayer with the ‘ishaa prayer.
