834
Musnad AhmedIt was narrated that Wahb as-Suwa"i said:
"Ali (رضي الله عنه) addressed us and said: Who is the best of this ummah after its Prophet ? I said: You, O Ameer al-Mu"mineen. He said: No, the best of this ummah after its Prophet is Abu Bakr, then "Umar (رضي الله عنهما), and it would not be far-fetched to suggest that tranquillity was uttered on the lips of "Umar (رضي الله عنه).
