1) Happiness and Delight
Optimism is the first effect of religious faith from the viewpoint of the creation of happiness and delight. A faithful man is optimistic about the world, the life and the creation. Religious belief gives a particular shape to man's attitude towards the world. As religion maintains that creation has a goal and that its goal is nothing but betterment and evolution, naturally religious belief affects the outlook of man and makes him optimistic about the system of the universe and the laws governing it.
The attitude of a faithful man to the universe is similar to the attitude of a man living in a country about which he is sure that its systems, laws and formations are just and fair, that those who are at the helm of its affairs are sincere and well-intentioned, and that in it opportunities of making advancement are available to everyone including himself. Such a man will naturally maintain that the only thing which may keep him or anyone else backward, is the lethargy and inexperience of the person concerned, and that he and all others owe a responsibility and are required to do their duty.
A faithful man will hold himself responsible for his backwardness and will not blame his country and its administration for that. He believes that if there is anything wrong, that is because he and others like him have failed to discharge their duty properly. This feeling will naturally arouse his sense of self-respect and impel him to move forward hopefully.
In contrast a disbeliever is in the universe like a man living in a country about which he believes that its system, laws and formations are unjust and corrupt, and that he has to accept them against his will. The heart of such a man will always be full of malice. He will never think of improving himself. He will think that where everything is wrong, his own uprightness will be of no use at all. Such a man never shall enjoy the world. For him the world will always be like a dreadful prison. That is why the Holy Qur'an says:
"He who turns away from remembering Me, his life will be burdensome." (Surah Ta Ha, 20:124)
Indeed it is faith which expands our life internally and saves us from the pressure of spiritual factors.
From the viewpoint of the creation of happiness and delight the second effect of religious faith is the illumination of heart. As man sees the world illuminated by the light of truth, his heart and soul are also illuminated. Faith is a lamp, which illuminates his inmost. In contrast, a disbeliever finds the world dark, dingy and meaningless, and as a result his own heart remains dark in his supposedly dark world.
The third effect of religious faith from the angle of happiness and delight is the expectation that good efforts produce good results.
From purely material point of view, the world is indifferent as to who goes along the right and just path and who goes along the wrong and unjust path. The result of a deed depends only on one thing, namely the amount of the effort put in it.
But according to the viewpoint of a faithful man the world is not indifferent and neutral in regard to the effort of those who do what is right and those who do wrong. The world's reaction to the effort of these two groups is not the same. The system of the creation supports those who make efforts for the cause of truth, justice and integrity.
The Holy Qur'an says:
"If you help Allah, He will help you." (Surah Muhammad, 47:7)
"Allah does not deprive the righteous of their reward " (Surah at-Tawbah, 9:120; Surah Hud, 11: 115; Surah Yusuf, 12:90)
The fourth effect of religious faith from the viewpoint of the creation of happiness and delight is mental satisfaction. Man by nature seeks success and the very idea of achieving it delights his heart. The apprehension of dark future frightens him and disturbs his peace. There are two things which make man happy and satisfied:
(i) Effort
(ii) Satisfaction in regard to the conditions prevailing in his environment.
The success of a student depends on two things: firstly, his own effort; and secondly, the suitability of the atmosphere of the school and the encouragement he receives from the school authorities. If a hard-working student has no confidence in the atmosphere of his school and in his examiners, he will all the year round be apprehensive of an unfair treatment and will be seized by a sense of anxiety.
Man knows his duty to himself. This aspect does not cause him any worry because what disturbs a man is a sense of doubt and uncertainty. Man is sure about all that concerns himself. What disturbs him and is not clear to him is his duty to the world.
The questions which perturb him most are: Are good deeds of any use? Do truth and honesty serve any useful purpose? Is deprivation the end of doing one's duty? These are the questions which cause anxiety and concern in the most dreadful form.
Religious faith restores man's confidence in the world and allays his distrust about its behaviour towards him. That is why we say that one of the effects of religious faith is mental peace.
Another effect of religious faith from the angle of delight and happiness is the better enjoyment of the pleasures known as spiritual pleasures. There are two types of pleasures that man can feel. Those of the first type are related to one of the five senses and are felt as the result of a contact between an organ of human body and an external object. The eye gets pleasure through seeing, the ear through hearing, the mouth through tasting and the sense of touch through touching. The other type of pleasures are those which are related to the spirit and the inner senses of man. They have no connection with any particular organ and are not obtained through contact with any external object. Such is the case with the pleasures which one gets from doing good or rendering service to others, from enjoying respect and popularity, or from one's success or the success of one's child. These pleasures are neither especially related to any organ nor are they under the direct influence of any external and material factor.
Spiritual pleasures are stronger and more lasting than material pleasures. The pleasure which the true worshippers of Allah get from their worship which they perform with humility and in which they are fully absorbed, is of this nature. In the language of religion it has been described as the 'taste of faith' and the 'flavour of faith'. Faith has a flavour which is better than and superior to every other flavour. Spiritual pleasure is enhanced when a virtuous act such as the acquisition of knowledge or rendering service to others is performed or success is achieved in a task actuated by religious sense. Any act which is performed for the sake of Allah is an act of worship and is Pleasurable.
