Salam. If any "official" refutation (if appropriate) is to be drafted, it can only be written by those who equal or exceed the station (in terms of language, adab, comprehension and elegance) of Sheikh Nuh Ha Mim Keller in order for such a work to be taken seriously. Otherwise, there is danger that a response will be seen as comparing Ihya and Mr. Ben! Here ends the lesson for today! Wa salam.
