 Despite this, the area had nevertheless produced several notable jurists of the Hanbali school of orthodox Sunni jurisprudence, which was the school of law most prominently practiced in the area.In fact, Ibn 'Abd-al-Wahhab's own family "had produced several doctors of the school," with his father, Sulaymān b. Muḥammad, having been the Hanbali jurisconsult of the Najd and his grandfather, ʿAbd al-Wahhāb, having been a judge of Hanbali law.Ibn 'Abd-al-Wahhab's early education consisted of learning the Quran by heart and studying a rudimentary level of Hanbali jurisprudence and theology as outlined in the works of Ibn Qudamah (d. 1223), one of the most influential medieval representatives of the Hanbali school whose works were regarded "as having great authority" in the Najd.
