Professor Hussein Ansarain answered the question that why have so many people fallen from God's grace? Said: many people are either in denial with the truth or do not want God, they never think about their goodness in this world or hereafter, they desire to be in the state of being unrestrained, Halal and Haram things have no place in their life and they don't care about them, there are also a great deal of people that if you tell them what's what, they accuse you of being insane, sick and nosy.
