Musannaf Ibn Abi Shaybah 34239 — The virtues of Ali bin Abi Talib

Sayyiduna Ali (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) wished to send me to the people of Yemen so that I might judge between them. I said: O Messenger of Allah (peace and blessings be upon him), I know nothing at all about judging. He said: He (peace and blessings be upon him) struck my chest with his hand and made this supplication: O Allah, guide his heart and make his tongue upright. After that I never had any doubt in judging between two people, up until today, as I sit in this place.
