Our identity is a mystery, we don't know for sure what was our being and condition before we came into existence in our mother's womb. We are not even sure where we are going. We live and die in ignorance. Even then we argue about God, religion, faith and some even deny the Creator. Haa ignorance !!
God has created man from a sperm-drop; and behold this same (man) becomes an open disputer! (Quran, 16:04)
