Human beings are created with a nature that takes pleasure in beauty, and with a desire to live in happiness and in well-being. Therefore, it is a completely natural human desire to be rid of unpleasant situations as quickly as possible, or to turn them into pleasant ones. In fact, being of a peaceable of mind and a healthy spirit are important factors for the health of the mind, as well as the body. However, when people act according to their feelings, desires and passions, without regard for the Qu'ran's teaching, they become oppressed by sadness, worry and fear. When one has no understanding of the nature of fate, and of what it means to put one's life in God's hands, and complete submission to His will as taught in the Qu'ran, he is in a state of constant struggle with the anxiety that arises from not knowing what will happen to him or to those close to him at any given time. Whereas, if he lives his life according to the religion that God has chosen for him, and according to the moral canons of the Qu'ran, he will never experience this anxiety or any other such difficulty. God proclaims this truth through His messengers when he says:

... all those who follow My guidance will not go astray and will not be miserable. But if anyone turns away from My reminder, his life will be a dark and narrow one … (Qur'an, 20:123-124)

It is true that God may test a person in this world with certain difficulties and worries. However, the believer does not give in to melancholy and pessimism when he is faced with such anxieties; he does not react emotionally. He knows that God is trying him to see how he will behave in difficulty, and that the solution is not to turn to weeping or sorrowful regret. The solution lies in seeking help from God, "Who responds to the oppressed when they call on Him and removes their distress" (Qur'an, 27:62), relying only on Him, and in being certain that God will hear his prayers and grant his requests. This is the promise of God to His servants:

Yes, the friends of God will feel no fear and will know no sorrow: those who believe and have done their duty, there is good news for them in the life of the world and in the hereafter. There is no changing the words of God. That is the great victory! (Qur'an, 10:62-64)

Moreover, God creates such trying moments of anxiety and difficulty for a very special reason. When someone looks with the eyes of faith, and sees the reasons behind all the beauty that God has created, he will be moved to compassion, and his contentment will increase. Therefore, submission to God brings a sense of calm to the spirit, and allows one to live with peace of mind.

Emotionalism, on the other hand, completely alienates people from the awareness of being in God's hands, and leads them to react to situations with excessive pleasure, or exaggerated pain and sorrow. God explains in the Qu'ran the wavering of such people between hopelessness and arrogance, and the difference between them and believers:

If We let man taste mercy from Us, and then take it away from him, he is despairing, ungrateful; but if We let him taste blessings after hardship has afflicted him, he says, "My troubles have gone away," and he is overjoyed, boastful except for those who are steadfast and do right actions. They will receive forgiveness and a large reward. (Qur'an, 11:9-11)
