The Second Issue:

Allāh Almighty said: ﴿فَإِنَّهُمۡ لَا یُكَذِّبُونَكَ وَلَـٰكِنَّ ٱلظَّـٰلِمِینَ بِـَٔایَـٰتِ ٱللهِ یَجۡحَدُونَ﴾ "Indeed, they do not deny you, but it is the wrongdoers who reject the signs of Allāh" [Al-An’ām 6:33]. In this Āyah, Allāh absolves them from the At-Takdhīb/denying the Prophet and attributes to them Al-Juḥūd/rejection of Allāh’s signs. This distinction [between denial and rejection] indicates that they are not the same. One key difference is that a person who rejects may internally believe something different from what they outwardly deny, as previously discussed (p. #). On the other hand, a person who denies holds in their heart exactly what they express outwardly of denial.
