Qur'an 6:137

وَكَذَٰلِكَ زَيَّنَ لِكَثِيرٍ مِّنَ ٱلْمُشْرِكِينَ قَتْلَ أَوْلَـٰدِهِمْ شُرَكَآؤُهُمْ لِيُرْدُوهُمْ وَلِيَلْبِسُوا۟ عَلَيْهِمْ دِينَهُمْ ۖ وَلَوْ شَآءَ ٱللَّهُ مَا فَعَلُوهُ ۖ فَذَرْهُمْ وَمَا يَفْتَرُونَ

Thus have their (so-called) partners (of Allah) made the killing of their children to seem fair unto many of the idolaters, that they may ruin them and make their faith obscure for them. Had Allah willed (it otherwise), they had not done so. So leave them alone with their devices.
