Musannaf Ibn Abi Shaybah

Hazrat Qasim bin Muhammad (may Allah have mercy on him) narrates that Hazrat Aisha (may Allah be pleased with her) said: I was reciting this poem as an example while Abu Bakr was making a decision. "And the one with a radiant face, by whose countenance rain is sought from the clouds; the refuge of orphans and the protector of widows." So Hazrat Abu Bakr (may Allah be pleased with him) said: That is the Messenger of Allah (peace and blessings be upon him).
