Abstract
Mulla Ali al-Qari is one of the most recent Sunni's scholars who have investigated faked hadiths in his book, al- A'srar al-Marfoua'ah Fi al-A'khbar al-Moudhoua. Significance of study about faked hadiths is that sometimes these kinds of hadiths cause invalidity of Islam. The reason why a critical review of such a book is significant is that he has analyzed and criticized reputed faked hadiths based on previous works in this regard, and in fact the author has profited from the earlier works and has examined fabricated traditions which are so famous among people. For receiving his intention, ha has utilized from some criteria such as attributing some things bad to the prophet, rejecting of hadith via intellectual evidences, experimental proofs, and so on. However, his criticism of some hadiths such as ''Ghadir's Hadith'' is incorrect. Since based on historical and rational reasons they are authentic and credible Hadiths. Hence, it is expected he criticize all hadith in a correct way.
