question #1 Sahih al-Bukhari 339, Book 7, Hadith 6 : What is the procedure for performing Tayammum when water is not available?

(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.”
