He is not questioned about what He does, but they will be questioned.
English Transliteration
La yusalu AAamma yafAAalu wahum yusaloona
Tafsir of Verse 23
He shall not be questioned as to what He does, but they shall he questioned.
He cannot be questioned for His acts, but they will be questioned (for theirs).
The next verse viz: لَا يُسْأَلُ عَمَّا يَفْعَلُ وَهُمْ يُسْأَلُونَ (He is not questioned of what He does, and they are questioned) probably reinforces the argument that anyone who is answerable for his actions to someone else cannot be God.
