Narrated `Ammar: The Prophet stroked the earth with his hands and then passed them over his face and the backs of his hands (while demonstrating Tayammum).

Narrated `Abdur Rahman bin Abza [??] : A man came to `Umar bin Al-Khattab and said, "I became Junub but no water was available." `Ammar bin Yasir said to `Umar, "Do you remember that you and I (became Junub while both of us) were together on a journey and you didn't pray but I rolled myself on the ground and prayed? I informed the Prophet about it and he said, 'It would have been sufficient for you to do like this.' The Prophet then stroked lightly the earth with his hands and then blew off the dust and passed his hands over his face and hands."

Narrated Sa`id bin `Abdur Rahman bin Abza: (on the authority of his father who said) `Ammar said so (the above Statement). And Shu`ba stroked lightly the earth with his hands and brought them close to his mouth (blew off the dust) and passed them over his face and then the backs of his hands. `Ammar said, "Ablution (meaning Tayammum here) is sufficient for a Muslim if water is not available."

Narrated Shaqiq bin Salama: I was with `Abdullah and Abu Musa; the latter asked the former, "O Abu `Abdur-Rahman! What is your opinion if somebody becomes Junub and no water is available?" `Abdullah replied, "Do not pray till water is found." Abu Musa said, "What do you say about the statement of `Ammar (who was ordered by the Prophet to perform Tayammum). The Prophet said to him: "Perform Tayammum and that would be sufficient." `Abdullah replied, "Don't you see that `Umar was not satisfied by `Ammar's statement?" Abu- Musa said, "All right, leave `Ammar's statement, but what will you say about this verse (of Tayammum)?" `Abdullah kept quiet and then said, "If we allowed it, then they would probably perform Tayammum even if water was available, if one of them found it (water) cold." The narrator added, "I said to Shaqiq, "Then did `Abdullah dislike to perform Tayammum because of this?" He replied, "Yes."

Narrated Al-A`mash: Shaqiq said, "While I was sitting with `Abdullah and Abu Musa Al-Ash`ari, the latter asked the former, 'If a person becomes Junub and does not find water for one month, can he perform Tayammum and offer his prayer?' (He applied in the negative). Abu Musa said, 'What do you say about this verse from Sura "Al-Ma'ida": When you do not find water then perform Tayammum with clean earth? `Abdullah replied, 'If we allowed it then they would probably perform Tayammum with clean earth even if water were available but cold.' I said to Shaqiq, 'You then disliked to perform Tayammum because of this?' Shaqiq said, 'Yes.' (Shaqiq added), "Abu Musa said, 'Haven't you heard the statement of `Ammar to `Umar? He said: I was sent out by Allah's Apostle for some job and I became Junub and could not find water so I rolled myself over the dust (clean earth) like an animal does, and when I told the Prophet of that he said, 'Like this would have been sufficient.' The Prophet (saying so) lightly stroked the earth with his hand once and blew it off, then passed his (left) hand over the back of his right hand or his (right) hand over the back of his left hand and then passed them over his face.' So `Abdullah said to Abu- Musa, 'Don't you know that `Umar was not satisfied with `Ammar's statement?' " Narrated Shaqiq: While I was with `Abdullah and Abu Musa, the latter said to the former, "Haven't you heard the statement of `Ammar to `Umar? He said, "Allah's Apostle sent you and me out and I became Junub and rolled myself in the dust (clean earth) (for Tayammum). When we came to Allah's Apostle I told him about it and he said, 'This would have been sufficient,' passing his hands over his face and the backs of his hands once only.' "

Narrated `Imran bin Husain Al-Khuza`i: Allah's Apostle saw a person sitting aloof and not praying with the people. He asked him, "O so and so! What prevented you from offering the prayer with the people?" He replied, "O Allah's Apostle! I am Junub and there is no water." The Prophet said, "Perform Tayammum with clean earth and that will be sufficient for you."
