Muslims do not at all…

Muslims do not at all deny visible (sensory) knowledge. Yet we accept that there is another sort of knowledge that is not directly accessible to us, and we need Prophets (Alayhim As-Salaam) and revealed books to know about this other type of knowledge. Very importantly, rejecting Mawjood (directly accessible and present) knowledge is as heretical as claiming the hidden knowledge that is only known through Revelation (i.e. claiming Wahy).
