Sahih Ibn Khuzaymah

Sayyiduna Abdur Rahman (may Allah be pleased with him) narrates that a man came to Sayyiduna Umar (may Allah be pleased with him) and said, "We become junub (in a state of major ritual impurity) and we do not have water (so how should we perform the prayer)?" Then he mentioned the incident of Sayyiduna Ammar bin Yasir (may Allah be pleased with him) along with him. He says that Hazrat Ammar said, "So I came to the Messenger of Allah (peace and blessings be upon him) and I told him about this incident." The Messenger of Allah (peace and blessings be upon him) said: "It would have been sufficient for you to do like this with your two hands." The Prophet (peace and blessings be upon him) struck his two hands on the earth, then shook them off, then blew on them, and then wiped his face and both hands with them. Imam Abu Bakr (may Allah have mercy on him) says that in the chain of this hadith, Imam Shu’bah has inserted Dhir (the narrator) between Salamah bin Kuhail and Sa’id bin Abdur Rahman. Imam Thawri narrated this hadith from Salamah, and he from Abu Malik and Abdullah bin Abdur Rahman bin Abza (may Allah be pleased with him), and they from Abdur Rahman bin Abza (may Allah be pleased with him). However, in the narration of Imam Thawri and Shu’bah, there is no mention of "shaking the dust off the hands."

Hazrat Shaqiq (may Allah have mercy on him) narrates that I was sitting with Sayyiduna Abdullah and Abu Musa (may Allah be pleased with them), when Abu Musa (may Allah be pleased with him) said, "O Abu Abdur Rahman, what is your opinion if a person becomes junub and does not find water for a month, should he continue to perform tayammum?" Sayyiduna Abdullah (may Allah be pleased with him) replied, "He will not perform tayammum (nor will he pray)." So Sayyiduna Abu Musa (may Allah be pleased with him) said, "Have you not heard the statement of Sayyiduna Ammar to Sayyiduna Umar (may Allah be pleased with him), (in which he says) that the Messenger of Allah (peace and blessings be upon him) sent me for an important task, and (on the way) I became junub and did not find water, so I rolled in the earth like an animal (and prayed). Then (after returning) I informed the Noble Prophet (peace and blessings be upon him), so the Messenger of Allah (peace and blessings be upon him) said: 'It would have been sufficient for you to strike your hands on the earth, then wipe them together, then wipe your face and both hands with them.'" Imam Abu Bakr (may Allah have mercy on him) says that in this hadith, the statement of the Prophet (peace and blessings be upon him) « ثُمَّ تَمْسَحَ » means to shake off the dust from both hands. (Because) "al-nafd" means to rub one palm with the other so that the dust on them falls off.
