The short answer
No, the Quran repeatedly demands proof, criticises people who follow their ancestors without thinking, and invites readers to reflect on the Quran itself and test it. The Prophet ﷺ reassured Companions troubled by doubts and defended Ibrahim's (AS) wish to see with his own eyes. What Islam discourages is not honest inquiry but pointless or hostile questioning and speaking without knowledge.
The Quran argues. To those who worship others besides Allah it says, "Produce your proof" 1, and it condemns people who reply to revelation with "we will follow that which we found our fathers doing", even though their fathers "understood nothing" 2. It tells believers not to "pursue that of which you have no knowledge", because hearing, sight and the heart will all be questioned 3. Blind imitation is exactly what it criticises.
It even invites readers to examine it: "Do they not reflect upon the Qur'an? If it had been from [any] other than Allah, they would have found within it much contradiction" 4.
Asking for certainty is not a failing. The prophet Ibrahim (AS) asked Allah to show him how He gives life to the dead. When asked, "Have you not believed?", he replied, "Yes, but [I ask] only that my heart may be satisfied" 5. The Prophet ﷺ commented, "We have more right to be in doubt than Abraham" 6, a humble way of saying that Ibrahim's question was not doubt at all. When Companions told him they felt thoughts too terrible to say aloud, he said, "That is the faith manifest" 7, meaning that their distress at such thoughts showed their faith.
There are limits, and it is honest to name them. The Quran told believers not to ask about things which, if made plain, would distress them, at a time when revelation could answer with new rulings 8. That is a warning against needless or hostile questioning, not against learning.
If you have questions, ask them sincerely, study, and speak to people of knowledge. Faith that has faced its questions is stronger for it.
To those who take other gods, "Produce your proof".
أَمِ ٱتَّخَذُواْ مِن دُونِهِۦٓ ءَالِهَةࣰۖ قُلۡ هَاتُواْ بُرۡهَٰنَكُمۡۖ هَٰذَا ذِكۡرُ مَن مَّعِيَ وَذِكۡرُ مَن قَبۡلِيۚ بَلۡ أَكۡثَرُهُمۡ لَا يَعۡلَمُونَ ٱلۡحَقَّۖ فَهُم مُّعۡرِضُونَ ٢٤
Or have they taken gods besides Him? Say, [O Muhammad], "Produce your proof. This [Qur'an] is the message for those with me and the message of those before me." But most of them do not know the truth, so they are turning away
Following ancestors who understood nothing is condemned.
وَإِذَا قِيلَ لَهُمُ ٱتَّبِعُواْ مَآ أَنزَلَ ٱللَّهُ قَالُواْ بَلۡ نَتَّبِعُ مَآ أَلۡفَيۡنَا عَلَيۡهِ ءَابَآءَنَآۚ أَوَلَوۡ كَانَ ءَابَآؤُهُمۡ لَا يَعۡقِلُونَ شَيۡـࣰٔ ا وَلَا يَهۡتَدُونَ ١٧٠
And when it is said to them, "Follow what Allah has revealed," they say, "Rather, we will follow that which we found our fathers doing." Even though their fathers understood nothing, nor were they guided
Do not pursue what you have no knowledge of; hearing, sight and heart will be questioned.
وَلَا تَقۡفُ مَا لَيۡسَ لَكَ بِهِۦ عِلۡمٌۚ إِنَّ ٱلسَّمۡعَ وَٱلۡبَصَرَ وَٱلۡفُؤَادَ كُلُّ أُوْلَٰٓئِكَ كَانَ عَنۡهُ مَسۡـُٔولࣰ ا ٣٦
And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart - about all those [one] will be questioned
Reflect on the Quran; if it were from other than Allah it would contain much contradiction.
أَفَلَا يَتَدَبَّرُونَ ٱلۡقُرۡءَانَۚ وَلَوۡ كَانَ مِنۡ عِندِ غَيۡرِ ٱللَّهِ لَوَجَدُواْ فِيهِ ٱخۡتِلَٰفࣰ ا كَثِيرࣰ ا ٨٢
Then do they not reflect upon the Qur'an? If it had been from [any] other than Allah, they would have found within it much contradiction
Ibrahim (AS) asked to see how Allah gives life, so that his heart would be satisfied.
وَإِذۡ قَالَ إِبۡرَٰهِـۧمُ رَبِّ أَرِنِي كَيۡفَ تُحۡيِ ٱلۡمَوۡتَىٰۖ قَالَ أَوَلَمۡ تُؤۡمِنۖ قَالَ بَلَىٰ وَلَٰكِن لِّيَطۡمَئِنَّ قَلۡبِيۖ قَالَ فَخُذۡ أَرۡبَعَةࣰ مِّنَ ٱلطَّيۡرِ فَصُرۡهُنَّ إِلَيۡكَ ثُمَّ ٱجۡعَلۡ عَلَىٰ كُلِّ جَبَلࣲ مِّنۡهُنَّ جُزۡءࣰ ا ثُمَّ ٱدۡعُهُنَّ يَأۡتِينَكَ سَعۡيࣰ اۚ وَٱعۡلَمۡ أَنَّ ٱللَّهَ عَزِيزٌ حَكِيمࣱ ٢٦٠
And [mention] when Abraham said, "My Lord, show me how You give life to the dead." [Allah] said, "Have you not believed?" He said, "Yes, but [I ask] only that my heart may be satisfied." [Allah] said, "Take four birds and commit them to yourself. Then [after slaughtering them] put on each hill a portion of them; then call them - they will come [flying] to you in haste. And know that Allah is Exalted in Might and Wise
"We have more right to be in doubt than Abraham."
Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "We have more right to be in doubt than Abraham when he said, 'My Lord! Show me how You give life to the dead.' He said, 'Do you not believe?' He said, 'Yes (I believe) but to be stronger in Faith
حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، وَسَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " نَحْنُ أَحَقُّ بِالشَّكِّ مِنْ إِبْرَاهِيمَ إِذْ قَالَ {رَبِّ أَرِنِي كَيْفَ تُحْيِي الْمَوْتَى قَالَ أَوَلَمْ تُؤْمِنْ قَالَ بَلَى وَلَكِنْ لِيَطْمَئِنَّ قَلْبِي}"
Of Companions troubled by terrible thoughts, the Prophet ﷺ said "That is the faith manifest".
It is narrated on the authority of Abu Huraira that some people from amongst the Companions of the Apostle (ﷺ) came to him and said:Verily we perceive in our minds that which every one of us considers it too grave to express. He (the Holy Prophet) said: Do you really perceive it? They said: Yes. Upon this he remarked: That is the faith manifest
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ جَاءَ نَاسٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَسَأَلُوهُ إِنَّا نَجِدُ فِي أَنْفُسِنَا مَا يَتَعَاظَمُ أَحَدُنَا أَنْ يَتَكَلَّمَ بِهِ . قَالَ " وَقَدْ وَجَدْتُمُوهُ " . قَالُوا نَعَمْ . قَالَ " ذَاكَ صَرِيحُ الإِيمَانِ " .
Do not ask about things which, if shown, would distress you, while revelation is coming down.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَسۡـَٔلُواْ عَنۡ أَشۡيَآءَ إِن تُبۡدَ لَكُمۡ تَسُؤۡكُمۡ وَإِن تَسۡـَٔلُواْ عَنۡهَا حِينَ يُنَزَّلُ ٱلۡقُرۡءَانُ تُبۡدَ لَكُمۡ عَفَا ٱللَّهُ عَنۡهَاۗ وَٱللَّهُ غَفُورٌ حَلِيمࣱ ١٠١
O you who have believed, do not ask about things which, if they are shown to you, will distress you. But if you ask about them while the Qur'an is being revealed, they will be shown to you. Allah has pardoned that which is past; and Allah is Forgiving and Forbearing
