It was narrated from ‘Ali (رضي الله عنه):
Shall I not tell you of the best of this ummah after its Prophet? [It is] Abu Bakr, and the second is ʼUmar (رضي الله عنهما). And if you wish, I shall name the third, Abu Ishaq said: `Abd Khair made it clear so that you would not have any doubts concerning what `Ali (رضي الله عنه) said.
