Wa kazaalika zaiyana likaseerim minal mushrikeena qatla awlaadihim shurakaaa'uhum liyurdoohum wa liyalbisoo 'alaihim deenahum wa law shaaa'al laahu maa fa'aloohu fazarhum wa maa yaftaroon

“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.”
