wikipedia says: Sunni Main article: Sunni In addition to the "Basic Code" of the Qur'an and Sunnah, traditional Sunni Muslims also add the consensus (ijma) of Muhammad's companions (sahaba) and Islamic jurists (ulema) on certain issues. In situations where no concrete rule exists in the sources, law scholars use qiyas — various forms of reasoning, including analogy, to derive law from the essence of divine principles and preceding rulings. The consensus of the community, public interest, and other sources are used as an adjunct to Sharia where the primary and secondary sources allow.[30] This description can be applied to the major schools of Sunni fiqh, which include the Hanafi, Shafi'i, Maliki and Hanbali. is this correct?
