Modern-day proponents of kalām such as Nuh Ha Mim Keller, a Sheikh in the Shadili Sufi Order, hold that the criticism of kalām from early scholars was specific to the Mu'tazila, going on to claim that other historical Muslim scholars such as Al-Ghazali and An-Nawawi saw both good and bad in kalām and cautioned from the speculative excess of unorthodox groups such as the Mu'tazilah and Jahmites.
