(Fatwa: 750/637=B/1429)
If anyone intentionally attributes a false hadith to the Prophet (صلى الله عايه وسلم) he will be called a cheat and a liar, but for this he, according to Shariah, will not be called Kafir (infidel). As far as Ilm-Ghaib is concerned, if you have objections or doubts regarding it, you are requested to study Bawariqul Ghaib (بوارق الغيب) written by Maulana Manzoor Nomani Sb, Izalatur Raib (ازالۃ الريب) by Maulana Sarfraz Khan Safdar, and others books like Futuhat-e-Nomania (فثوحاث نعمانيه).
Note: What do you mean by ?wrong Hadith?? And for what purpose has it been quoted?
