Ibn Abd al-Wahhab

Recently, Yasir Qadhi described ibn Wahhab as an extremist and mentions that he saw himself as enlightened and the rest of the world in darkness. He cites a passage from the the following book: ad-Durar as-Saniyyah fi al-Ajwibah an-Najdiyyah.

However, others say his translation is inaccurate. Has Yasir Qadhi forgotten the Arabic language?

Here is my translation:
Let me inform you about myself: (I swear) by God, of whom there is no other.
Certainly, I sought knowledge and I think (he) who knows me (knows) I have a (deep) knowledge.
(Actually, at) that time I (did) not know the (true) meaning of no deity except God, and I (did) not know the (true) meaning of the religion of Islam; before (the coming of) this good fortune, which is from (the grace of) God.
And likewise my teachers, not one of them knew (the meaning of the above).
