What is the opinion of Abu `Abdur-Rahman about performing Tayammum when no water is available, as instructed by the Prophet Muhammad (saw)?
 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."
