‏أحسن الله إليكم What does it mean if we pass the Ijazah final exam for Level one? What does it allow us to do with it if we pass it? بارك الله فيكم

Your knowledge is what allows you to teach not an ijazah. The inazah is testimony that u studied all of this and it connects chains of narrations for what you have studied and in hadeeth all the way to the Prophet in the books of hadeeth. Also u have the ijazah ammah for what u have not studied and in the future when u study them u already have the connected chain.
