Surah Al-An'am 6:140
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.
Translation: Saheeh International
Tafsir
They are losers who slay read qatalū or qattalū their children by burying them alive in folly out of ignorance without knowledge and have forbidden what God has provided them of what has been mentioned in calumny against God. Verily they have gone astray and are not guided.
