Shia scholar Nematullah al-Jazairi says in his book:
ويعجبني نق مباحثة جرت بين شيخنا البهائي قدس الله روحه وبين علماء مصر وهو اعلمهم وافضلهم وقد كان شيخنا البهائي يظهر لذلك العالم انه على دينه
I would like to mention a discussion that was held between our Shaikh Bahai, and some scholar of Egypt, and he was the most knowledgeable and superior amongst them, and Shaikh Bahai would present himself to that scholar that he is upon the [Sunni] scholar’s religion.
Anwar al-Numania, Vol. 1, p. 73
