673 - Abu Dawud narrated to us, he said: Shu'bah narrated to us, from Al-Hakam, who heard Dharr bin 'Abdullah narrating from the son of 'Abd al-Rahman bin Abza, from his father, who said: "A man came to 'Umar and mentioned that he was on a journey, became in a state of major ritual impurity (janaba), and could not find water. He ('Umar) said: 'He does not pray.' Then 'Ammar said: 'Do you not remember, O Commander of the Faithful, when you and I were in a military detachment and we became in a state of major ritual impurity and did not find water? As for you, you did not pray, and as for me, I rolled in the dust and prayed. When we came to the Messenger of Allah (saw), we mentioned that to him, and he said to you: "As for you, it was not appropriate for you to leave the prayer," and as for you, O 'Ammar, "it was not appropriate for you to roll as a beast rolls; it would have been sufficient for you" - and the Messenger of Allah (saw) struck the ground with his hand into the dust, then said like this, blew into it, and wiped his face and his hands up to the joint, and it does not include
(147) the forearms."
