"O son of my sister, by Allah, I used to see the new moon, then the new moon, then the new moon, i.e., three moons in two months, and a fire was not kindled in the house of Messenger of Allah (ﷺ). "I ('Urwah) said, "O my aunt, what were your means of sustenance?" She said; "Dates and water. But it (so happened) that Messenger of Allah (ﷺ) had some Ansar neighbours who had milch animals. They used to send Messenger of Allah (ﷺ) some milk of their (animals) and he gave that to us to drink."
