Al-an-Situ - The Quran of the Prophet Muhammad

These were jewish jinns they had believed in musa and the ta'ra. When they heard the religion or the quran they knew that this was from the same being who had sent down the ta’ra so they converted and they went to their people calling them to islam. Even if the people of iraq from the furthest corner know you are upon the truth these two conversions are not out of the blue. There's a huge symbolism here that the furthest corners of this world and beyond this world and that is the world of the jinn.
