On that account We ordained for the Children of Isra`il that if any one killed a person - unless it be for murder or for spreading mischief in the land - it would be as if he killed the whole humanity: and if any one saved a life, it would be as if he saved the whole humanity. Then although there came to them Our messengers with clear (guidance), yet, even after that, many of them continued to commit excesses in the land. (5:32)
PRINCIPLE 1 SAVE A LIFE - SAVE HUMANITY
Islam believes in serving humanity and saving lives based on humane values.No difference of cast, colour ,religion or ethnic background is taken into consideration.The only factor behind serving people is that they are all creation of One God and progeny of single parents, Adam and Eve.
