Humanity and islam
The Holy Quran expressly declares that the human race is one family. All of us are the children of Adam and Eve, whether our skin is white or black. The differences in our physical features, colors, complexions, languages, dresses, customs and the ways of living. I think just those people who settled in hot tropical zones grew to be black and those who settle in cold climate grew to be white in their complexion. There is no difference between people but only piety. The prophets, the guides whom god sent to all the people, instructed these all people to one thing is worshiping the one god and every people has a prophet and they were inviting to the same thing. They have not given a certain worship for black people or for white people. That means we are the same and we have to deal each other humanly without mocking at each other.
Finally I just want to say all the people have two sides bad and good and we have to believe that the good side always predominates in the bad side even if there is a bad person it is impossible that you can not find a good side inside him or the desire to be a good person so when you advice someone evil you have to say you are a good person but the people who surround you make you like you are and you are going to see the difference and finally the humanity is the message of all the religions.
