In the past, a person shared some fabricated hadiths in facebook group , but he doesn’t know it’s fabricated and when he came to know , he has a huge fear & Also knows about the hadith tat who ever tell lie about our prophet salla Allahu Alaihi wassallam Then let tat person take place in hell , Now he’s much feared about his past action..as it’s long back, the person could not even able to delete wat he spread … he has done out unknowingly… What is the expiation for this sheik???
