Alhamdulillah. One: It is obligatory on a Muslim to preserve his faith and belief. Emphasis on the security of one's creative instincts and thoughts. He escapes from doubts and temptations with his religion and heart. Because the hearts are weak. And the suspicions are snatching. The hearts are snatched away with a little glamor. The heretics and the misguided adorn the doubts with glamor. But in fact they are baseless and weak suspicion. It is not permissible to read the books of heretics and heretics, or to look at the books of polytheism and superstition, or to look at other perverted scriptures, or to look at the books of atheists and hypocrites, or the websites that promote their anti-Islamic thoughts and false suspicions. It may be permissible only for the person who has the knowledge of the Shari'ah and he wants to respond to them by studying these and to expose their misconceptions and he has that ability and full competence. On the other hand , if a person who does not have knowledge of Shariah reads these, then in most cases he will get into trouble , his heart will be weakened and the doubts that he will face will shake his heart. This has happened to many ordinary people. On the contrary, it has happened in the case of many Taliban scholars who were not qualified in this field. In the end, some of them have gone astray. Naujubillah. Those who read such books are often deceived into thinking that their hearts are stronger than their doubts. Suddenly he discovers that his heart has been drinking these doubts in a way that he did not even think about. For this reason, the statement of Alem-Ulama and Salafe Salehin is that it is haraam to read and study these books. We have mentioned the opinion of the scholars in question no. 92781 . Two: Islam must be known from its own source. The great and main source of Islam: Quran-Sunnah. Islam has given dignity to conscience and thought. This dignity is reflected in many verses. Some sentences are repeated ten times in the Qur'an. Such as لَعَلَّكُمْ تَعْقِلُونَ (so that you may understand) , لِقَوْمٍ يَتَفَكَّرُونَ ( for those who think) , لِقَوْمٍ يَفْقَهُونَ ( for those who understand). God has called us to think about the Qur'an ; He said: "This is a blessed Book which We have revealed to you , so that the people may ponder deeply its verses and the people of understanding may take heed." [Surah Chad , 36:29] Do they not think about themselves ? Allah has created the heavens and the earth and all that is between them in truth and for a specific term. But most people (after death) refuse to meet their ****. "[Surah Ar-*** , 30: 6] The inmates of Hell have condemned the gods for not benefiting from their conscience. He describes them: "They will say , ' If we had heard or understood , we would not have been in Hell. ' " [ Surah Mulk , 6:10] He added: The eyes would be such that they could hear, because the eyes are not (actually) blind , but the innermost part of the chest is (actually) blind. "[Surah Al-Hajj , 22:46] ; In this verse Allaah informs us: “In the creation of the heavens and the earth, and in the alternation of night and day, there is indeed a sign for men of understanding ; Our ****! You have not created these in vain. We narrate Your Glory. So save us from the torment of Hell. "[Surah Al-Imran , 3 : 190-191] Shaykh Sa'di said : There are signs in the creation of the earth and in the rotation of night and day for those who reflect. Through this he has inspired his servants to think about these , to perceive their signs and to think about their creation. The word "pattern" is left out indefinitely in the verse. "Such a thing" is not said in this way: for the purpose of pointing out the extent and universality of the patterns. Because there are some wonderful signs in them which overwhelm the visitor , satisfy the thinker , draw the hearts of the truthful , awaken the enlightened consciences towards the divine things. And it is not possible for any creature to fully know the details of the patterns that are included in them. All in all, the chain of greatness , vastness , passage and motion embedded in them : all bear witness to the greatness of the great Creator , the vastness of his kingdom and the vastness of his power. The skill and perseverance in them , the novelty of the creation , the subtlety of the action prove it all - God is Wise , He puts everything in place and His knowledge is wide. Among these, the benefits for the creation of the universe prove the magnitude of God's mercy , the magnitude of His grace, the extent of His welfare, and the need for gratitude to Him. All this proves that the heart of the servant is to be associated with his Creator and Provider , to strive hard for His satisfaction and not to associate anything with Him ; Those who have no ability to do anything for themselves or for others. In these verses, Allah has called the wise ones special. Those who are conscientious. Because they are the ones who benefit from it , they are the seers of conscience , not with the eyes. Then Allah mentions the characteristics of the wise that they remember Allah while standing , sitting and lying down. It includes all kinds of remembrance of the mouth, remembrance of the heart. This will include standing prayer ; Sit down if you can't stand , lie down if you can't sit. And they reflect on the creation of the heavens and the earth so that they may prove their purpose. This proves that meditation is an act of worship which is an attribute of God's friends who know God. When they think about it, they know that God did not create them in vain. Then they said: "Our ****! Thou hast not created it in vain. Thou art pure from that which is not fit for Thy dignity. Nay , Thou hast created them with the truth , for the sake of truth and to include the truth. Save us by saving us from sin. Give us the tawfiq of good deeds so that we may be saved from the fire . Then I went to Ayesha (R) and said to Ubaid bin Umayr (R): Do you understand that it is time for you to come to see us ? Then he said: Keep these words of yours. Ubaid bin Umayr (R) said: Tell us what you have seen in the life of the Messenger of Allah, may Allah bless him and grant him peace , he said : Wasallam) said to me , Ayesha! Tonight I will be the son of my **** Leave it for a while. I said , by God! I like to be with you and do what makes you happy. Then he got up, purified himself, and began to pray. He kept crying during the prayer. His lap got wet from crying. Even then he kept crying. His beard got wet from crying. Even then he kept crying. The ground got wet crying! (Before Fajr) Bilal came to inform him of the prayer. When he saw her weeping , he said: O Messenger of Allah! Why are you crying God has forgiven all your past sins! He said: Shall I not be a servant of thanksgiving ? A verse has been revealed to me tonight. Destruction is for those who have read it , but have not thought about it : , 3: 190] [Sahih Ibn Hibban (2/26) , see: As-Silsila As-Sahiha (1/148)] The great thinker and writer Abbas Mahmud Al-Aqqa has a book on the subject entitled: التفكير فريضة إسلامية ( Thoughts are obligatory in Islam). The book can be read.
