Wahhab’s jurisprudence narrowed Sunni legal sources to Qur’an and hadith alone.

Evidence

Of the four major sources in Sunni Fiqh – the Qur’an, the Sunna, ‘Ijma (juristic consensus) and Qiyas (analogical reasoning) – Ibn ‘Abd al-Wahhab’s writings emphasized the Qur’an and Sunna. He used ‘ijma only “in conjunction with its corroboration of the Qur’an and hadith” (and giving preference to the ijma of Muhammad’s companions rather than the ijma of legal specialists after his time), and qiyas only in cases of extreme necessity. He rejected deference to past juridical opinion (taqlid) in favor of independent reasoning (ijtihad), and opposed using local customs. — Wikipedia contributors, Wahhabism, 115
