Sincere questioning aimed at better understanding strengthens faith, but aimless, stubborn, or intrusive questions about hidden matters can harm it. The principle is reflection and contemplation, not excessive or obsessive curiosity.
In the rich teachings of Islam, questioning and seeking knowledge are not only not condemned but are strongly encouraged. The Holy Quran repeatedly invites humans to ponder (tafakkur), use their intellect (ta'aqqul), and reflect deeply (tadabbur) on the divine signs (ayat) in the universe and within themselves. This invitation signifies that faith in Islam is not a blind, purely imitative belief, but rather one built upon understanding, comprehension, and intellectual conviction. Many Quranic verses emphasize the importance of intellect and reflection with phrases like "that you may reflect" (لَعَلَّکُمْ تَتَفَکَّرُونَ), "for a people who reason" (لِقَوْمٍ یَعْقِلُونَ), and "signs for those of understanding" (آیاتٌ لِّأُولِی الْأَلْبَابِ). Therefore, asking questions aimed at achieving a deeper understanding, removing ambiguities, and strengthening the foundations of faith is not dangerous; it is essential and highly beneficial. Such questioning saves the believer from ignorance and intellectual stagnation, leading them towards certainty (yaqin) and inner peace. This process is akin to constructing a building where each question and answer adds a firmer brick, making it more resilient against the storms of doubt and ambiguity. However, a crucial point emphasized by the Quran and the Sunnah of Prophet Muhammad (PBUH) is the distinction between constructive and destructive questioning. When questioning devolves into unhealthy curiosity, obsessive thoughts (waswas), pointless fault-finding, or an attempt to impose hardship upon oneself and others, it can indeed harm faith. The Holy Quran explicitly states in Surah Al-Ma'idah, verse 101: "O you who have believed, do not ask about things which, if made manifest to you, would trouble you." This verse clearly sets limits on the type and quantity of questioning. "Things which, if made manifest to you, would trouble you" can include matters that are, firstly, related to the ghayb (unseen) whose details Allah has chosen not to reveal to humanity, and excessive curiosity in them would only lead to confusion and distress. Secondly, questions asked out of stubbornness, mockery, or with the intention of imposing more difficulties upon oneself and others, rather than to understand the truth. A prominent example of this type of questioning can be seen in the story of the Children of Israel and the matter of the cow (Surah Al-Baqarah, verses 67 to 71). Allah commanded them to sacrifice a cow to identify a murderer, but instead of simple obedience, they began asking excessive details about its color, age, and characteristics, making the task increasingly difficult for themselves until they almost failed to find it. This example demonstrates how excessive and misplaced questioning can deviate from the path of obedience and wisdom, creating hardship instead of ease. The dangers of excessive questioning include: Firstly, fostering endless doubt and obsession that plunges the believer into a whirlpool of confusion, pulling them away from peace and certainty. When the sole purpose is to find fault and uncover flaws in beliefs, rather than to reach the truth, the mind never finds tranquility. Secondly, losing focus on primary actions and duties. An individual constantly preoccupied with fruitless questions and useless arguments neglects worship, ethics, and serving humanity. Thirdly, venturing into areas beyond human comprehension or whose details Allah has chosen not to reveal (such as the essence of God, precise details of the Day of Judgment, etc.). Drowning in these matters can lead to misunderstanding, innovation (bid'ah), and even apostasy. Fourthly, sometimes excessive questioning stems from a lack of heartfelt submission to divine truths. Faith, after the stage of reflection and conviction, reaches a stage of submission and reliance on God (tawakkul). One who continues to question endlessly out of doubt or stubbornness at this stage has not truly submitted to Allah's command. To achieve balance in questioning, the goal should always be to better understand and strengthen faith. Questions should be asked with humility and with the intention of finding answers, not for baseless challenge. Furthermore, for answers, one should refer to authentic religious sources (the Quran and sound Sunnah) and righteous scholars. True scholars are those who themselves possess deep understanding and can provide convincing answers with wisdom and logic. Ultimately, it must be understood that not everything in this world will be revealed to humanity, and a part of faith involves submission to the unknowns that Allah has kept hidden in His divine knowledge. This submission is not out of weakness, but out of trust and reliance on Allah's boundless knowledge and wisdom. Strong faith is one that combines intellect and heart; it is inquisitive but moves within the bounds of etiquette and purpose, leading not to distress, but to peace and profound knowledge.
O you who have believed, do not ask about things which, if made manifest to you, would trouble you. But if you ask about them while the Qur'an is being revealed, they will be made manifest to you. Allah has pardoned that which is past; and Allah is Forgiving and Forbearing.
And [recall] when Moses said to his people, "Indeed, Allah commands you to slaughter a cow." They said, "Do you take us in ridicule?" He said, "I seek refuge in Allah from being among the ignorant."
Who remember Allah while standing or sitting or [lying] on their sides and contemplate the creation of the heavens and the earth, [saying], "Our Lord, You did not create this in vain; exalted are You [above such a thing]; then protect us from the punishment of the Fire."
Once, among the students of the Sheikh, there was a man known for his excessive questioning and endless scrutiny. Whatever lesson the Sheikh taught, he would raise hundreds of minute and grand questions, sometimes out of curiosity and sometimes out of contention. The Sheikh would answer with kindness and patience, but one day, with a smile, he said: "O son, know that pure ocean water, when poured into many tiny and narrow vessels, instead of quenching thirst, only brings more thirst and causes one to lose themselves in the search for a single drop. Knowledge is similar. If you constantly pursue every minute detail of it and neglect the broader principles, peace will leave your heart, and you will drown in a sea of doubt and obsession. Faith is like a great river that flows peacefully, not a spring that gushes from every rock, where you constantly seek its source from every stone. Act upon what you have known, and entrust what you do not know to the wisdom of the Merciful God, for peace lies in wise submission, not in endless scrutiny." When the student heard this, he lowered his head in thought and realized that the knot of his problem was not in finding an answer to every question, but in being content with the truth and acting upon what he knew.
