Ok i just read one of his premises:
v. Divine revelation is certain knowledge (this type of certain knowledge is known as al-‘ilm al-qat’i) which can be proven using deductive arguments.
Ah crap, now we're in trouble. Which certain knowledge shall i follow the bible, torah, quran or satanic bible? oh wait its only the quran, revealed to a supposedly unintelligent desert merchant.
Ok i guess facts (that don't contradict quran) are now what i shall accept as CERTAIN KNOWLEDGE!!
