ٱنظُرْ كَيْفَ كَذَبُوا۟ عَلَىٰٓ أَنفُسِهِمْ ۚ وَضَلَّ عَنْهُم مَّا كَانُوا۟ يَفْتَرُونَ
7:54; 11:22.
Commentary:
The words, they lie against themselves, mean that by denying that they ascribed co-partners to God they will utter a lie which will prove their guilt. By making this statement they will, in other words, admit that ascribing co-partners to God is an evil deed. Thus their very denial will be a confession of their guilt.
The words, see how, express astonishment at the way in which they, while trying to deny the charge, will be led into a confession of guilt.
7:54; 11:22.
