Belief in karma is an important element in superstitious eastern religions such as decadent Hinduism, Buddhism and Jainism. Karma is a Sanskrit word meaning "action" or "movement". In Indian religions, karma is conceived of as "the law of cause and effect". According to those who believe in karma, in the future people will experience the consequences of whatever they have done in the past. Good comes from good, and evil from evil. It therefore follows that the situation they are in today is the result of the past.

According to this belief, however, what is meant by "the past" is the life that a person lived before their current life; what is meant by "the future" is their next life back on this Earth that will begin (or so it is claimed), after death. The reason for this is that the belief in karma is based on a belief in reincarnation—the belief that after death, people return to the world in a different body, and that this process of death and rebirth is continuous. It therefore follows that someone who believes in karma believes that in the so-called life they will have after death, whatever successes they have, whatever position in society they occupy and whatever way of life they enjoy will have been determined by how they behaved in their previous life and on their degree of morality in that life.

For example, someone who is rich and successful in this life is being rewarded with wealth for having been a good person in their previous life. In the same way (according to the concept of karma), someone who is poor, crippled or a failure in this life will have done bad things in their previous life and is now reaping the reward for those actions. In fact, it is claimed by those who subscribe to this superstitious belief system that people may take the form of plants or animals in their successive lives, depending on the nature of the evil they have done. At first sight it might appear that a belief in karma would provide a strong incentive for people to adopt attractive moral qualities, since they will want to enjoy the best possible conditions when they are reborn into this world. However, the belief in reincarnation and other superstitious concepts fostered by religions which espouse karma (such as Hinduism and decadent Buddhism), are contrary to human logic, human nature and the human conscience. Thus, the laws and practices of these religions cannot possibly endow people with good moral qualities; they cannot bring individuals peace of mind, inner confidence or happiness. The poor living conditions and the injustice prevalent in those countries where these religions are common or where they have, in fact, been adopted as the national religion, quite clearly demonstrate the truth of this.

One of the main reasons why some of the teachings of Hinduism and Buddhism attract attention is the interest shown in them by certain world-famous film stars and musicians. Some of these famous people have their photographs taken wearing Buddhist robes in Tibet, or they claim to have found peace of mind in meditation. Another thing that makes people interested in these religions is the aura of mystery and mysticism with which they are associated in the mind of the public.

But the great majority of people who are influenced by this mystical aura and who make a belief in karma the foundation for their way of life do not carry out any detailed investigation into these philosophies and do not think about them carefully enough. This is because they are too focused on the positive spiritual and moral aspects to see that these religions in their decadent conditions contain many beliefs that are inconsistent, illogical, and contrary to human nature and conscience, or perhaps they simply prefer to ignore these anomalies altogether.

However, anyone who wishes to escape from the difficult and depressing life they are leading and who sincerely wants all humanity to be able to live a life full of happiness and inner tranquility ought to make an effort to find the right way. Therefore, they should carefully investigate the philosophies by which they are influenced and should be inwardly certain which path is the most correct, the wisest and the one that best accords with their conscience.

Karma is derived from a religion based on myths, superstitions and practices that defy reason. The only way for people to live happily and enjoy peace of mind in this life and in their eternal life after death is for them to have faith in Allah and to act in accordance with the dictates of the Qur’an. The Qur’an is the book of truth revealed by our Lord, Allah, for the sake of thinking people; it is our only guide to salvation, bringing people from darkness into light. The only true way is to put into practice the ethics of the Qur’an and to fear Allah, the Creator of the heavens and the earth, Who keeps people from wickedness, discord, cruelty, oppression, intolerance, despair, pessimism, unhappiness and every kind of reprehensible act, and to live in accord with the Sunnah of His Noble Messenger, Muhammad, may Allah bless him and grant him peace.
