ذَٰلِكُمْ بِأَنَّهُ إِذَا دُعِيَ اللَّهُ وَحْدَهُ كَفَرْتُمْ ۖ وَإِنْ يُشْرَكْ بِهِ تُؤْمِنُوا ۚ فَالْحُكْمُ لِلَّهِ الْعَلِيِّ الْكَبِيرِ
This has come upon you because when God alone was invoked you disbelieved; but when partners were associated with Him, you believed. But judgement belongs to God, the all-high and supreme.

That namely the chastisement which you find yourselves in is because during the life of this world when God was invoked alone you would disbelieve in His Oneness; but if partners were ascribed to Him you would believe you would accept such idolatry. So the judgement to chastise you belongs to God the Exalted above His creation the Great the Tremendous.

ذَٰلِكُمْ بِأَنَّهُ إِذَا دُعِيَ اللَّهُ وَحْدَهُ كَفَرْتُمْ ۖ وَإِنْ يُشْرَكْ بِهِ تُؤْمِنُوا ۚ فَالْحُكْمُ لِلَّهِ الْعَلِيِّ الْكَبِيرِ
