A follow up, there are these quotes going around from Ibn Hajar's Fath al Bari where he quotes Imam Qurtubi criticizing Kalam and who also quotes Imam Juwayni who recanted from Kalam, is this true? Does this show all three weren't Ashari's? What is the response? The argument that he referred to Ashari's in the third person is very bad looking back, I don't know why I thought that was a good argument, I've heard Imam Razi does this as well who didn't have a deathbed conversion wahhabisrefuted.wordpress.com/2018/12/26/did-fakhr-al-din-al-razi-repent-from-ashari-aqidah/
btw, Imam Qurtubi had nothing against kalam for those who are capable either:
159 Those who hide the Clear Signs and Guidance We have sent down, after We have made it clear to people in the Book, Allah curses them, and the cursers curse them -
Those who hide the Clear Signs and Guidance We have sent down,
Allah reports that anyone who hides the Clear Signs and Guidance is cursed. Scholars disagree about what is meant by that. It is said that the Jewish rabbis and Christian monks are the ones who concealed their knowledge of the coming of Muhammad, may Allah bless him and grant him peace, and the Jews concealed the command about stoning. It is said that it means everyone who con- ceals the truth, and so it is general to all who conceal any knowl- edge of the din of Allah which should be made known. That is explained by the words of the Prophet, "If anyone is asked about knowledge which he knows and conceals it, Allah will bridle him with a bridle of Fire on the Day of Rising." (Ibn Majah)
That is counterbalanced by the statement of 'Abdullah ibn Mas'ud, "You should not tell people a hadith which is beyond the grasp of their intellects lest it be as a trial for some of them." He also said, "Relate to people according to their ability to under- stand. Do you want Allah and His Messenger to be denied?" This applies to some areas of knowledge, like kalam and the like which not everyone can grasp.
