No, I haven't said you're a Kafir. I'll not judge you. Allah will Judge you. Only Allah can. If you don't disrespect the three caliphs and mother Ayesha, I've no problem with you. I hope its not famous shia Takiya. To abuse people who are much more pious and beyond our imagination is a big sin. Allah will hold those accountable on the day of Qayamat. The shias I'm referring to, they were in my college. Then I had Shias in my university. I tried the same card with them and it played. They after trusting me started talking crap about those beloved personalities. Someone who abuses his mother is no wonder cursed and a Lanati of highest order.
Anyone who abuses the first three caliphs and Hazrat Ayesha (R) are uneducated and 'jaahil' people.
