Dawae Nabuwat And Takfeer
I am student of knowledge….i will cover only 1 portion of ur qn… 1st of all: I will tell you very simple thing…. A muslim can not deny Quran….okay u as well know it… Now in Quran there are 3 primary things in believing prophet saw that.1)He was both prophet and messenger..2)He was send for whole humanity until qiyamah…3)He is last of prophets… Now word used for 3rd pt. Used in Quran is khatam….its not khatim Khatim is فاعل and khatam is اسم …. When its said that anyone is khatim of this jamaat…it can mean yes he has finished this or that thing…. It can be used as well to say that his level is such that it seems he has finished this thing…. But when khatam is used it is noun….it can not be used in this figurative sense….. Means in this verse Allah says that he is khatim himself and placement of prophet saw is such that of seal….. So chances of anyone to be prophet is not according to Quran….so its kufr 100% to omit what Quran says…. 2nd of takfir….i am not personally exposed to what Ghamidi sahab has to say about that… But its very logical to say anyone you are doing kufr after preaching them….but respectfully…
