Verse 12

ذَٰلِكُم بِأَنَّهُۥٓ إِذَا دُعِىَ ٱللَّهُ وَحْدَهُۥ كَفَرْتُمْ وَإِن يُشْرَكْ بِهِۦ تُؤْمِنُوا۟ فَٱلْحُكْمُ لِلَّهِ ٱلْعَلِىِّ ٱلْكَبِيرِ

This is because when God alone was called upon, you disbelieved, and when a partner was set up besides Him, you believed. Therefore, judgment belongs to God, The Exalted, The All Magnificent.
