'Ammar, it would have been enough for you (to do) so. He then stuck only one stroke on the ground with both his hands; he then stuck one with the other; then wiped his face and both arms up to half the forearms and did not reach the elbows.

Abu Dawud said: This is also transmitted by Waki' from al-A'mash from Salamah b. Kuhail from 'Abd al-Rahman b. Abza.

It is also transmitted through a different chain by Jarir from al-A'mash from Salamah from Sa'id b. 'Abd al-Rahman b. Abza from his father.
Sunan Abi Dawud Book 1, Hadith 323
← Previous Hadith While I was with 'Umar, a man came to him and said: We live at a place (where water is not found) for a month or two (what should we do, if we are sexually defiled). 'Umar said: So far as I am concerned, I do not pray until I find water. 'Ammar said: Commanded of the faithful, do you not remember when I and you were among the camels (For tending them)? There we became sexually defiled. I rolled down on the ground. We then came to the Prophet (ﷺ) and I mentioned that to him. He said: It was enough for you to do so. Then he struck the ground with both his hands. He then blew over them and wiped his face and both hands by means of them up to half the arms. 'Umar said: 'Ammar, fear Allah. He said: Commander of the faithful, if you want, I will never narrate it. 'Umar said: Nay, by Allah, we shall turn you from that towards which you turned (i.e. you have your choice).
