سَيَقُولُ ٱلَّذِينَ أَشْرَكُوا۟ لَوْ شَآءَ ٱللَّهُ مَآ أَشْرَكْنَا وَلَآ ءَابَآؤُنَا وَلَا حَرَّمْنَا مِن شَىْءٍ ۚ كَذَٰلِكَ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ حَتَّىٰ ذَاقُوا۟ بَأْسَنَا ۗ قُلْ هَلْ عِندَكُم مِّنْ عِلْمٍ فَتُخْرِجُوهُ لَنَآ ۖ إِن تَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ أَنتُمْ إِلَّا تَخْرُصُونَ

Those who associated [others] with Allāh will say, "If Allāh had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but misjudging."

Al-An'am 148

أَلَآ إِنَّ لِلَّهِ مَن فِى ٱلسَّمَـٰوَٰتِ وَمَن فِى ٱلْأَرْضِ ۗ وَمَا يَتَّبِعُ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ شُرَكَآءَ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ

Unquestionably, to Allāh belongs whoever is in the heavens and whoever is on the earth. And those who invoke other than Allāh do not [actually] follow [His] "partners." They follow not except assumption, and they are not but misjudging.

Yunus 66

قُلْ هَلْ مِن شُرَكَآئِكُم مَّن يَهْدِىٓ إِلَى ٱلْحَقِّ ۚ قُلِ ٱللَّهُ يَهْدِى لِلْحَقِّ ۗ أَفَمَن يَهْدِىٓ إِلَى ٱلْحَقِّ أَحَقُّ أَن يُتَّبَعَ أَمَّن لَّا يَهِدِّىٓ إِلَّآ أَن يُهْدَىٰ ۖ فَمَا لَكُمْ كَيْفَ تَحْكُمُونَ

Say, "Are there of your 'partners' any who guides to the truth?" Say, "Allāh guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] with you - how do you judge?"

Yunus 35

وَيُعَذِّبَ ٱلْمُنَـٰفِقِينَ وَٱلْمُنَـٰفِقَـٰتِ وَٱلْمُشْرِكِينَ وَٱلْمُشْرِكَـٰتِ ٱلظَّآنِّينَ بِٱللَّهِ ظَنَّ ٱلسَّوْءِ ۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِ ۖ وَغَضِبَ ٱللَّهُ عَلَيْهِمْ وَلَعَنَهُمْ وَأَعَدَّ لَهُمْ جَهَنَّمَ ۖ وَسَآءَتْ مَصِيرًا

And [that] He may punish the hypocrite men and hypocrite women, and the polytheist men and polytheist women - those who assume about Allāh an assumption of evil nature. Upon them is a misfortune of evil nature; and Allāh has become angry with them and has cursed them and prepared for them Hell, and evil it is as a destination.

Al-Fath 6

إِنْ هِىَ إِلَّآ أَسْمَآءٌ سَمَّيْتُمُوهَآ أَنتُمْ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلْطَـٰنٍ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَمَا تَهْوَى ٱلْأَنفُسُ ۖ وَلَقَدْ جَآءَهُم مِّن رَّبِّهِمُ ٱلْهُدَىٰٓ

They are not but [mere] names you have named them - you and your forefathers - for which Allāh has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance.
