God created man in darkness and ignorance. People need a beacon to get out of this darkness and find their destination. That light will show him the way out of darkness. Whose influence will he realize, what work should he do, what path should he follow - earthly, or otherworldly path? Do you have to be addicted to yourself, or do you have to be in love with God? Without the light of knowledge man cannot know these things and without good thoughts the light of knowledge cannot be obtained. In many places in the Holy Qur'an, Allah has commanded tafakkur, tadabbur, najar and itibar. These words are almost synonymous, the real meaning is to think about honest things. Allaah says (interpretation of the meaning): “Surely you will be asked about hearing, seeing and thinking” (Surah Bani Israa'il: 36). It is mentioned in the hadith, "One hour of saintly thought is better than one year of worship."
In Islam, honest thinking and good speech are very important. Because when a person thinks badly, speaks obscene language and speaks unnecessarily, it is manifested in his actions. That is why honest qualities are lost in him. The desire for good times decreases. The brain and soul are considered to be the main source of human thought. This soul and brain, which is working all the time with good thoughts, can remember Allah, be free from negligence and sinfulness. The Prophet (peace and blessings of Allaah be upon him) said: There is a piece of your body which, if it is right, then the whole body will be right, and if it is inferior, then the whole body will be inferior. Know, this is Kalb (Mishkat Sharif). Allah says, "Whatever you say or think, there is a guardian to protect it" (Surah Qaf: 17).
Sadhuchinta is the origin of marifat (knowledge of identity), halat (status) and amal (Hazrat Imam Ghazzali). For example, the hereafter is permanent and the hereafter is temporary. By this thought, it is better to know that the hereafter is better than the present. People asked Jesus (pbuh), O Ruhullah, is there anyone else in the world like you? He said, Yes, there is; Every word of which is the remembrance of Allah, silence is spent only in good thoughts and advice from every point of view and that person is like me. Sacred thinking means thinking about one's own nature and actions. It is the duty of the believer to first think and inquire as to which of his own dispositions is evil and which of his deeds is sinful. Some of the sins occur with the help of the seven limbs. Such as eyes, limbs etc. Some work relates to the whole body; Such as the evil nature of the heart. Looking at the heart with the remembrance of Allah, with the eye, with devotion, looking at the creation of Allah, with contempt towards the transgressor, is done in the duty of soul and eye. God has created wealth for the comfort of man. So it is the benefit of good thoughts to donate this wealth to the poor or to spend to alleviate the needs of others. Each of these thoughts produces a positive effect on the heart, which may save a person from eternal sin. Because even though people are unable to look at the bright sun, they do have the ability to see the rays that spread on the earth's surface. The Prophet (peace and blessings of Allaah be upon him) said: The beauty of Islam is the person who abandons useless words and deeds. Paying too much attention to trivial, insignificant and unimportant matters; Such as listening to rumors, believing the words and prophecies of people who provoke anxiety and discouragement - these negative thoughts lead to dementia, anxiety and trouble. Happiness and peace of mind are also lost. On the contrary, a smiling face, smiling face, gentle speech and good character are the most effective ways to win the hearts of people and make a place for oneself in the court of God's love. The most important thing that will attract an honest person in the heart of a person is truthfulness, kindness and tenderness. Only man can acquire these knowledge of good and evil through great thought by his senses. God has endowed man with these senses and feelings so that he may examine the imaginations and beliefs that come to mind. If it is pure, it will turn into action and if it is wrong, it will be refrained from. What will a person do after falling into this sinful dark world, whichever way he goes, only good thoughts can help him reach his destination - the path that has been combined with the Holy Paradise.
