Hamran bin Aban حمران بن أبان · The Book of Purification and its Sunnah

"Aishah dropped a necklace and stayed behind to look for it. Abu Bakr went to 'Aishah and got angry with her for keeping the people waiting. Then Allah revealed the concession allowing dry ablution, so we wiped our arms up to the shoulders. Abu Bakr went to 'Aishah and said: 'I did not know that you are blessed.'"

"We did dry ablution with the Messenger of Allah, (wiping our arms) up to our shoulders."
