Sometimes when I see a person who does an act of major kufr I try to evaluate if there is udhr in that scenario because I’m scared if I takfir unjustly it’ll come back to me but if I don’t then I’ll be a kafir for not labeling a disbeliever as one.Should I ignore if idk the scenario has udhr or not?
