I agree with u that God is no begin and no End but the Question is Who created God??? This question is inherently false and self contradictory. If we were to say for the sake of argument -that some one created God then they would ask who created the creator of the creator? Then who created the creator of the creator of the creator? And so on,................... This is irrational and impossible. Quran tells us:
