Ghamdi Sahab's Viewpoint On Takfeer
You can refer to 23 series on takfir for more detailed view of Ghamidi sb In short Ghamidi sb refers to this hadith that whats in the heart is known to Allah so no one can know the reality of intentions or belief. There is an hadith which Ghamidi sb consider authentic words are as follows Any person who called his brother: “O unbeliever” (has in fact done an act by which this unbelief) would return to one of them. If it were so, as he asserted (then the unbelief of man was confirmed but if it was not true), then it returned to him (to the man who labeled it on his brother Muslim). Ghamidi sb said in 23 series that if a person says he is muslim and we labelled them non muslim then it return to us. In case of Ahmadi, they have wrong understanding of the verse. We will highlight their wrong understanding only.
