The Quran says. that if any person kills any human being whether it is a Muslim or Non Muslim (irrespective of the race, caste, colour or creed) if any person kills any human being, unless it is for murder, or for spreading mischief in the land, it is as though he has killed the whole of humanity.
And if anyone saves another human being, whether it be a Muslim or Non Muslim (irrespective of any caste, colour or creed), it is as though he has saved the whole of humankind.
Thus, Islam has prescribed a moral code in order to ensure that Universal Brotherhood prevails in the world.
THE PEOPLE THOSE WHO ARE NOT FOLLOWING ABOVE ARE NOT TRUE FOLLOWERS OF ISLAM.
