'A'isha used to say to 'Urwa
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 fire was not kindled in the house of Allah's Messenger (ﷺ). I ('Urwa) said: Auntie, then what were your means of sustenance? She said: Dates and water. But it (so happened) that Allah's Messenger (ﷺ) had some Ansar as his neighbours and they had milch animals and they used to send to Allah's Messenger (ﷺ) some milk of their (animals) and he served that to us.
