'Imran b. Husain reported

I was with the Messenger of Allah (ﷺ) in a journey. We travelled the whole of the night, and when it was about to dawn, we got down for rest, and were overpowered (by sleep) till the sun shone. Abu Bakr was the first to awake amongst us. and we did not awake the Messenger of Allah (ﷺ) from his sleep allowing him to wake up (of his own accord). It was 'Umar who then woke up. He stood by the side of the Messenger of Allah (ﷺ) and recited takbir in a loud voice till the Messenger of Allah (ﷺ) woke up. When he lifted his head, he saw that the sun had arisen; he then said: Proceed on. He travelled along with us till the sun shone brightly. He came down (from his camel) and led us in the morning prayer. A person, however, remained away from the people and did not say, prayer along with us. After having completed the prayer, the Messenger of Allah (ﷺ) said to him: O, so and so, what prevented you from observing prayer with us? He said: Apostle of Allah! I was not in a state of purity. The Messenger of Allah (ﷺ) ordered him arid lie performed Tayammum with dust and said prayer. He then urged me to go ahead immediately along with other riders to find out water, for we felt very thirsty. We were traveling when we came across a woman who was sitting (on a camel) with her feet hanging over two leathern water bags. We said to her: How far is water available? She, said: Far, very far, very far. You cannot get water. We (again) said: How much distance is there between (the residence of) your family and water? She said: It is a day and night journey. We said to her: You go to the Messenger of Allah (ﷺ). She said: Who is the Messenger of Allah? We somehow or the other managed to bring her to the Messenger of Allah (ﷺ) and he asked about her, and she informed him as she had informed us that she was a widow having orphan children. He ordered that her camel should be made to kneal down and he gargled in the opening (of her leathern water-bag). The camel was then raised up and we forty thirsty men drank water till we were completely satiated, and we filled up all leathern water-bags and water-skins that we had with us and we washed our companions, but we did not make any camel drink, and (the leathern water-bags) were about to burst (on account of excess of water). He then said: Bring whatever you have with you. So we collected the bits (of estable things) and dates and packed them up in a bundle, and said to her: Take it away. This is meant for your children, and know that we have not its any way done any loss to your water. W hen she came to her family she said: I have met the greatest magician amongst human beings, or he is an apostle, as he claims to be, and she then narrated what had happened and Allah guided aright those people through that woman. She affirmed her faith in Islam and so did the people embrace Islam.
