﴿ ٱنظُرْ كَيْفَ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ ۖ وَكَفَىٰ بِهِۦٓ إِثْمًۭا مُّبِينًا ﴾

“Behold how they attribute their own lying inventions to God - than which there is no sin more obvious.”

Consider in amazement how they invent falsehood against God in that way and that suffices for a clear an evident sin.
