It is true that they fought each other. However, while some claim that it was due to extreme taŽassub to their madhhabs, other sources indicate that it was due to Aqidah, the Hanafis of Khurasan at that time being MuŽtazila, and the ShafiŽis of Ahl as-Sunnah, and that fighting erupted due to preservation of what was thought to be a correct Aqidah. Wa'Allahu aŽlam.
