﴿ إِنَّمَا يَأْمُرُكُم بِٱلسُّوٓءِ وَٱلْفَحْشَآءِ وَأَن تَقُولُوا۟ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ ﴾

“and bids you only to do evil, and to commit deeds of abomination, and to attribute unto God something of which you have no knowledge.”

he only commands you to evil and indecency and that you should speak against God what you do not know. Because of his audacity toward God he induces you to speak falsely about God.
