This work happened to be in my way of seeking light in the darkness of ignorance. I found that human happiness is in simplifying variables and worries to one. One generator of all, no matter how things look complicated and need sophisticated solutions, the solution of all is in pursuing the piety as he demanded and as we feel it righteous when we're alone thinking. Allah the Almighty, the most merciful and most gracious, he created us from none, he haven't created us to make us miserable, he is as close to us as saying please give me such or such, and when he created this universe, he wrote that everything we're going to ask for is given to us already. He implies in Quraan that what he wrote for each of us is going to happen no matter how we fight to change it. He also implies that changing fate is possible by several methods including: asking him directly, asking for forgiveness since we're punished by our sins, bowing to him and sincerely worshiping him, helping the poor and people in need, being patient and accepting, and mentioning his name in ourselves very often.
