The three criteria related to the sanad are; a. dhabit narrator, b. Fair narrator, c. Points one and two must be owned by all narrators in the sanad. He did not include the continuity of the chain as a criterion for the validity of the hadith, because according to him this element had actually entered into the criteria for point two. Criteria related to matan, are: a) Matter of hadith is not syā (one or more of the narrators contradict their narration with a narrator who is more accurate and more reliable), b) Matan hadith does not contain illat qadhihah, i.e. deficiencies that are known by hadith experts so they reject the history of a narrator. 2) Al-Ghazali's method in critiquing the hadiths goes through four steps, namely testing with the Qur'an, testing with Hadith, testing with historical facts, and testing with scientific truth.
