knowledge versus ignorance

بَلِ ٱتَّبَعَ ٱلَّذِينَ ظَلَمُوٓا۟ أَهْوَآءَهُم بِغَيْرِ عِلْمٍ ۖ فَمَن يَهْدِى مَنْ أَضَلَّ ٱللَّهُ ۖ وَمَا لَهُم مِّن نَّـٰصِرِينَ

But those who wrong follow their [own] desires without knowledge. Then who can guide one whom Allāh has sent astray? And for them there are no helpers.

وَمِنَ ٱلنَّاسِ مَن يَشْتَرِى لَهْوَ ٱلْحَدِيثِ لِيُضِلَّ عَن سَبِيلِ ٱللَّهِ بِغَيْرِ عِلْمٍ وَيَتَّخِذَهَا هُزُوًا ۚ أُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ مُّهِينٌ

And of the people is he who buys the amusement of speech to mislead [others] from the way of Allāh without knowledge and who takes it [i.e., His way] in ridicule. Those will have a humiliating punishment.

أَلَمْ تَرَوْا۟ أَنَّ ٱللَّهَ سَخَّرَ لَكُم مَّا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَأَسْبَغَ عَلَيْكُمْ نِعَمَهُۥ ظَـٰهِرَةً وَبَاطِنَةً ۗ وَمِنَ ٱلنَّاسِ مَن يُجَـٰدِلُ فِى ٱللَّهِ بِغَيْرِ عِلْمٍ وَلَا هُدًى وَلَا كِتَـٰبٍ مُّنِيرٍ

Do you not see that Allāh has made subject to you whatever is in the heavens and whatever is in the earth and amply bestowed upon you His favors, [both] apparent and unapparent? But of the people is he who disputes about Allāh without knowledge or guidance or an enlightening Book [from Him].

أَمَّنْ هُوَ قَـٰنِتٌ ءَانَآءَ ٱلَّيْلِ سَاجِدًا وَقَآئِمًا يَحْذَرُ ٱلْـَٔاخِرَةَ وَيَرْجُوا۟ رَحْمَةَ رَبِّهِۦ ۗ قُلْ هَلْ يَسْتَوِى ٱلَّذِينَ يَعْلَمُونَ وَٱلَّذِينَ لَا يَعْلَمُونَ ۗ إِنَّمَا يَتَذَكَّرُ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ

Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord, [like one who does not]? Say, "Are those who know equal to those who do not know?" Only they will remember [who are] people of understanding.
