قَدْ خَسِرَ ٱلَّذِينَ قَتَلُوٓا۟ أَوْلَٰدَهُمْ سَفَهًۢا بِغَيْرِ عِلْمٍۢ وَحَرَّمُوا۟ مَا رَزَقَهُمُ ٱللَّهُ ٱفْتِرَآءً عَلَى ٱللَّهِ ۚ قَدْ ضَلُّوا۟ وَمَا كَانُوا۟ مُهْتَدِينَ
They are losers who besottedly have slain their children without knowledge, and have forbidden that which Allah bestowed upon them, inventing a lie against Allah. They indeed have gone astray and are not guided.
