﴿ 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 how they invent falsehood against God, by claiming to purify their souls of their attributes when they have not been purified, or, because of the existence of their souls, by falsely ascribing God's attributes to their own souls.
