if you are posting this yourself, you probably should go back to studying. if this is the response by arnold on facebook, then: ---- of course, imam abu'l Hasan al-ash'ari was a student of jubbayi. and he - imam abu'l Hasan - abandoned mutazilah to become a sunni and then aided the madh'hab of ahl al-sunnah so much that eventually, it became synonymous with his madh'hab. regardless of specific issues, the elephant in the room, is that the mutazilah denied many beliefs which could not be explained rationally or which appeared to contradict the literal meaning of qur'anic verses. like the issue of ru'yah - seeing Allah ta'ala. wa yansawna'n na'yima idha ra'awhu fa ya khusrana ahli'l iytizali. ---- the madh'hab of the ash'ayirah is the madh'hab of ahl al-sunnah. and when we speak of imam abu'l hasan al-ash'ari, we speak POST his mutazili period. many texts that mention his conversion, also mention that it was on account of an argument with jubbayi, 'and then he abandoned that madh'hab'. in the link you have posted AND someone has already underlined: if you read the thabat, it reaches imam ahl al-sunnah, abu'l Hasan; and about HIM, it says - first he studied with jubbayi and then he abandoned his madh'hab to aid the ahl al-sunnah. many companions abandoned disbelief - many converts to islam in our time abandoned their own previous beliefs. would you say that their islamic viewpoint evolved from their previous belief? my diagram and contention is just as you have quoted: those who came to be known as ash'ari and maturidi WERE/ARE the ahl al-sunnah - regardless of imam abu'l hasan joining in late, but he came back to ahl al-sunnah and aided this madh'hab. ---- Allah ta'ala knows best.
