Ignorance versus Knowledge

قَدْ خَسِرَ ٱلَّذِينَ قَتَلُوٓا۟ أَوْلَـٰدَهُمْ سَفَهًۢا بِغَيْرِ عِلْمٍ وَحَرَّمُوا۟ مَا رَزَقَهُمُ ٱللَّهُ ٱفْتِرَآءً عَلَى ٱللَّهِ ۚ قَدْ ضَلُّوا۟ وَمَا كَانُوا۟ مُهْتَدِينَ

They will have lost who killed their children in foolishness without knowledge and prohibited what Allāh had provided for them, inventing untruth about Allāh. They have gone astray and were not [rightly] guided.

ثُمَّ جَعَلْنَـٰكَ عَلَىٰ شَرِيعَةٍ مِّنَ ٱلْأَمْرِ فَٱتَّبِعْهَا وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ لَا يَعْلَمُونَ

Then We put you, [O Muḥammad], on an ordained way concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know.
