Volume 5, Book 57, Number 56:
Narrated Ubaida:
Ali said (to the people of ‘Iraq), “Judge as you used to judge, for I hate differences (and I do my
best ) till the people unite as one group, or I die as my companions have died.” And narrated Sad that
the Prophet said to ‘Ali, “Will you not be pleased from this that you are to me like Aaron was to
Moses?”
