there is no imaginary God. Allah is the sole lord of this world. if you dont believe in Allah then you will have so many question you cant answer them. like from where this world came, from wehreyou came. and to where you will go, how come such complext machine like human kind can just originate on its own. there are plenty you will be wandering all teh time if you dont believe in Allah but only if you are thoughtful. if you are like a selfish man who think mast raho masti mein , aag lage basti mein then there is answer to you but soon very soon you will thetruth revealed ot you and you will face the deeds you did throughtout your life.
