Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates that once we were traveling with the Prophet Muhammad (peace and blessings be upon him) until the time of morning approached. The Prophet (peace be upon him) ordered us to camp. The people fell asleep and slept until the sun had risen high. The first to wake up was Sayyiduna Abu Bakr (may Allah be pleased with him). No one would wake the Prophet (peace be upon him) from sleep until he woke up himself. When Sayyiduna Umar (may Allah be pleased with him) woke up and saw that the sun had risen high, he sat by the head of the Prophet (peace be upon him) and began to say the takbir in a loud voice until the Prophet (peace be upon him) woke up. When he woke up and saw that the sun had risen high, he departed from there. He traveled a little until the sun was shining brightly. Then he camped and led us in prayer. One of those present stayed apart and did not pray with us. When the Prophet (peace be upon him) finished the prayer, he asked: "What prevented you from praying with us?" He replied: "O Messenger of Allah! I am in a state of major impurity (janabah)." The Prophet (peace be upon him) ordered him: "Perform tayammum with earth and pray." Then the Prophet (peace be upon him) sent me ahead with some riders to search for water, as we were extremely thirsty. We were traveling when we saw a woman who had two water skins with her. We asked her: "Where is water?" She replied: "There is no water here." We asked: "How far is it between us and water?" She replied: "A day and a night's journey." We said: "Come with us to the Messenger of Allah." She asked: "Where is the Messenger of Allah?" So we brought her to the Prophet (peace be upon him). She told the Prophet (peace be upon him) the same thing she had told us, but she added that she was the mother of orphan children. The Prophet (peace be upon him) ordered that her water skins be opened from the bottom. Forty thirsty people drank from them until we were all satisfied. We filled every vessel and bowl we had. We gave water to our companion for ghusl, but we did not give water to our camels. Then the Prophet (peace be upon him) ordered: "Bring whatever you have." Then the Prophet (peace be upon him) gathered pieces of bread, dates, and so on for her, tied them in a bundle, and said: "Go and feed this to your family, and know that we have not decreased anything from your water." When she returned home, she said: "I have met the greatest magician, or he is a Prophet, as the people say." The narrator says that because of this woman, Allah guided her tribe. The woman became Muslim, and her tribe also became Muslim. Imam Bukhari (may Allah have mercy on him) has narrated this report from Abu al-Walid with this chain, while Imam Muslim (may Allah have mercy on him) has narrated it from Ahmad bin Sa'id al-Darimi.
