Abdur Rahman bin Abzi (may Allah have mercy on him) says: A man came to Sayyiduna Umar (may Allah be pleased with him) and said: I am in a state of janabah and have not found water. Sayyiduna Umar (may Allah be pleased with him) said: Then do not pray. Sayyiduna Ammar (may Allah be pleased with him) said: O Commander of the Faithful, do you not remember when you and I were in a caravan (on a journey)? We both became junub and did not find water. You did not pray, but I rolled on the ground like an animal and then prayed. The Noble Prophet (peace and blessings be upon him) said: It would have been sufficient for you to strike your hands on the earth, then blow on them, and wipe your face and both hands. Sayyiduna Umar (may Allah be pleased with him) said: Ammar! Fear Allah! Sayyiduna Ammar (may Allah be pleased with him) said: If you wish, I will not narrate this hadith. Hakam (may Allah have mercy on him) says: Abdur Rahman bin Abzi (may Allah have mercy on him) narrated this hadith to me in the same way, and in the chain of Hakam, these words are also present: Sayyiduna Umar (may Allah be pleased with him) said to Sayyiduna Ammar (may Allah be pleased with him): You are responsible for the narration you have reported.
