Ibn 'Abd al-Rahman b. Abza reported on the authority of his father this incident from 'Ammar. He said:
This would have been enough for you, and the Prophet (ﷺ) struck the ground with his hand. He then blew it and wiped with it his face and hands. Being doubtful Salamah said: I do not know (whether he wiped) up to the elbows or the wrists.
