Summary of the concepts of Ahl al-Sunnah: Knowledge is clear insight for calling to Allah. Whoever rushes into calling to Allah without knowledge calls without insight; he will never achieve his objective, even if he claims sincerity in his calling, and his call will bear no fruit. Allah the Exalted said: “Say: This is my Way: I call on Allah with sure knowledge. I and whosoever followeth me - Glory be to Allah! - and I am not of the idolaters.” (12:108) “Say: This is my Way: I call on Allah with sure knowledge. I and whosoever followeth me - Glory be to Allah! - and I am not of the idolaters.” (12:108) Thus, He stipulated insight, which is the requirement of knowledge, for pursuing the path of calling to Allah.
