“The Messenger of
Allah
(ﷺ) entered upon a man among the Ansar when he was watering
his
garden. The Messenger of Allah (ﷺ) said to him: ‘If you have any
water that has been kept overnight in a water skin, then give us some
to drink, otherwise we will drink by putting out mouths in the
basin.’
He said: ‘I have water that has been kept in a water
skin. So he went
and we went with him, to the shelter, where he
milked a sheep for him
and (mixed it with) the water that had been
kept overnight in a water
skin. He drank from it, then he did
likewise for his Companion who was
with him.”
