Narrated Muhammad bin Usamah bin Zaid:
from his father, that he said: "When the Messenger of Allah (ﷺ) became weak, I marched and the people marched upon Al-Madinah. I entered upon the Messenger of Allah (ﷺ) and he was unable to speak (because of weakness), so he did not say anything. So the Messenger of Allah (ﷺ) began to place his hands upon me and then raise them up, so I knew he was supplicating for me."
