Islam clearly establishes your duties and rights in all those relationships. Islam establishes a clear system of worship, civil rights, laws of marriage and divorce, laws of inheritance, code of behavior, what not to drink, what to wear, and what not to wear, how to worship God, how to govern, the laws of war and peace, when to go to war, when to make peace, the law of economics, and the laws of buying and selling. Islam is a complete code of life. Islam is not practiced in the mosque only, it is for daily life, a guide to life in all its aspects: socially, economically, and politically. Islam is complete constitution. Thus Islam keeps the Muslim away from confusion, because Islam is logical and rational. Allah is one. Allah is one Allah has no sons. Allah is not associated with trinity. Allah does not kill to save.
