Can anyone verify this reference (Tabari I guess?) and also post the exact translation (alongwith the Arabic if possible) and give the book/page #
Ibn Jareer and Ibn Abdul Birr narrated from Muhammad Bin K`ab:
"A man asked Hadrat Ali (radiallahu anhu) a masala. He (Ali) replied to it. The man said that it is not so. But it is like this (and he explained to Ali). Hadrat Ali (radiallahu anhu) said: ‘You are correct, and I have erred. Indeed above every man of knowledge is one who knows more."
