I embraced Islam and my (ignorance of the) religion made me anxious (to learn the essentials). I came to Abu Dharr. Abu Dharr said: The climate of Medina did not suit me. The Messenger of Allah (ﷺ) ordered me to have a few camels and goats. He said to me: Drink their milk. (The narrator Hammad said): I doubt whether he (the Prophet) said: "their urine." Abu Dharr said: I was away from the watering place and I had my family with me. I would have sexual defilement and pray without purification. I came to the Messenger of Allah (ﷺ) at noon. He was resting in the shade of the mosque along with a group of Companions. He (the Prophet) said: Abu Dharr. I said: Yes, I am ruined, Messenger of Allah. He said: What ruined you ? I said: I was away from the watering place and I had family with me. I used to be sexually defiled and pray without purification. He commanded (to bring) water for me. Then a black slave-girl brought a vessel of water that was shaking as the vessel was not full. I concealed myself behind a camel and took bath and them came (to the Prophet). The Messenger of Allah (ﷺ) said: Abu Dharr, clean earth is a means of ablution, even if you do not find water for ten years. When you find water, you should make it touch your skin.

Abu Dawud said: This is transmitted by Hammad b. Zaid from Ayyub. This version does not mention the words "their urine." This is not correct. The words "their urine" occur only in the version reported by Anas and transmitted only by the people of Basrah.
