Abu Qais, the freed slave of Amr bin al-As, said Amr bin al-As was in a battle. He then narrated the rest of the tradition. He then said: He washed his armpits and other joints where dirt was found, and he performed ablution like that for prayer. Then he led them in prayer. He then narrated the tradition in a similar way but did not mention of tayammum. Abu Dawud said: This incident has also been narrated by al-'Awzai on the authority of Hassan bin Atiyyah. This version has the words: Then he performed tayammum.
