وَكَذَلِكَ زَيَّنَ لِكَثِيرٍ مِّنَ الْمُشْرِكِينَ قَتْلَ أَوْلاَدِهِمْ شُرَكَآؤُهُمْ لِيُرْدُوهُمْ وَلِيَلْبِسُواْ عَلَيْهِمْ دِينَهُمْ وَلَوْ شَاء اللّهُ مَا فَعَلُوهُ فَذَرْهُمْ وَمَا يَفْتَرُونَ
[6:137]
And thus their associates have made fair seeming to most of the polytheists the killing of their children, that they may cause them to perish and obscure for them their religion; and if Allah had pleased, they would not have done it, therefore leave them and that which they forge.
Even so, in the eyes of most of the pagans, their "partners" made alluring the slaughter of their children, in order to lead them to their own destruction, and cause confusion in their religion. If Allah had willed, they would not have done so: But leave alone them and their inventions.
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.
