I asked the Prophet (ﷺ) about tayammum. He commanded me to strike only one stroke (i.e. the strike the ground) for (wiping) the face and the hands.
Sunan Abi Dawud Book 1, Hadith 327
← Previous Hadith It would have been enough for you to strike the ground with you hands and then wipe them your face and your hands (up to the wrists). He then narrated the rest of the tradition.

Abu Dawud said: This is also transmitted by Shu'bah from Husain on the authority of Abu Malik. He said: I heard 'Ammar saying so him his speech, except that in this version he added the words: "He blew." And Husain b. Muhammad narrated from Shu'bah on the authority of al-Hakam and in this version added the words:"He (the Prophet) struck the earth with his plans and blew."

Sunan Abi Dawud Book 1, Hadith 326 Next Hadith → Qatadah was asked about tayammum during a journey. He said: A traditionist reported to me from al-Sha'bi from 'Abd al-Rahman b. Abza on the authority of 'Ammar b. Yasir who reported the Messenger of Allah (ﷺ) as saying: (He should wipe) up to the elbows.
