Quran 6:140 from Surah Al-An'aam on Divine Marvels.
قَدۡ خَسِرَ ٱلَّذِينَ قَتَلُوٓاْ أَوۡلَٰدَهُمۡ سَفَهَۢا بِغَيۡرِ عِلۡمٖ وَحَرَّمُواْ مَا رَزَقَهُمُ ٱللَّهُ ٱفۡتِرَآءً عَلَى ٱللَّهِۚ قَدۡ ضَلُّواْ وَمَا كَانُواْ مُهۡتَدِينَ
English translation: Certainly (are) lost those who killed their children (in) foolishness without knowledge and forbid what (bas been) provided (to) them (by) Allah inventing (lies) against Allah Certainly they have gone astray and not they are guided-ones
