Surah Al-An'aam, Verse 137
وَكَذَٰلِكَ زَيَّنَ لِكَثِيرٍۢ مِّنَ ٱلْمُشْرِكِينَ قَتْلَ أَوْلَٰدِهِمْ شُرَكَآؤُهُمْ لِيُرْدُوهُمْ وَلِيَلْبِسُوا۟ عَلَيْهِمْ دِينَهُمْ ۖ وَلَوْ شَآءَ ٱللَّهُ مَا فَعَلُوهُ ۖ فَذَرْهُمْ وَمَا يَفْتَرُونَ
Translation — Sahih International
And likewise, to many of the polytheists their partners have made [to seem] pleasing the killing of their children in order to bring about their destruction and to cover them with confusion in their religion. And if Allah had willed, they would not have done so. So leave them and that which they invent.
