"In King Suleiman´s time, Djinn spirits were trap and forced to be in human fold without their consent and that when they bind a Djinn in that time conjurers usually exchange something with the spirit to make wishes. But today´s conjurer´s Djinn spirits are bind willingly to serve. I have worked with them being Marid, Shaitan, Ifrits & Ghul. People who know nothing about them tell that Shaitans are evil etc. even Ghul but they are like us, they procreate, get married, eat and die. There are also believer and unbeliever Djinns of all tribes. My Ifrit is unbeliever but he respects my beliefs. My Shaitan is a believer Djinn and even my Ghul. So I don´t like when people just read something and generalizing that all Djinns are evil etc. You must work with them to know the truth. They are advanced being. They already know you before getting to you. If you have an evil heart, they know that, but having them and working with them is a great responsibility. Not like as Hollywood portrait them to be."
