These aspects include daily activities and rituals such as Namaaz, food etiquettes, respect for elders, marriage ceremonies, peaceful and friendly behavior towards neighbors, friends, relatives, and numerous aspects of daily life. thus we can say that the Koran is the code of conduct, a reference book for the Muslim community to lead a peaceful and content life while doing good deeds, for which they shall be rewarded in the life, hereafter, or after death.
Existentialism is not a religion; it is a movement which began in the early 18th century, by a group of scholars. The movement is atheistic as it does not believe in God as the supreme power governing the actions and occurrences of the world. Existentialism is a way of life which determines that the actions of a person are based on free will. It states that morals, value and ethics in the life of an individual necessitate form the individual's experiences of the world, and as such are based on personal perceptions. The movement is known to have begun by scholars like Soren Kierkegaard, who emphasizes on the occurrence of truth, rejecting the system of Hegelianism. He states that each individual has to pass through three stages in life.
