In Quran, the brotherhood of man and the equality of woman with man socially, economically and spiritually are emphasized. Man is a member of a great fraternity.
Woman is the counterpart of man.
Selflessness and service are the ideals which a Muslim is enjoined to follow. The essence of Islam is the service of the suffering humanity. The Prophet of Islam also was a great lover of the doctrine of Ahimsa . Injuring people in any way or destroying any living creature is reprehensible. He taught that men would be specially judged on the day of judgment with regard to their cruel treatment of dumb creatures.
