Your god is one God. But those who do not believe in the Hereafter - their hearts are disapproving, and they are arrogant.
The Saheeh International Quran Translation
إِلَٰهُكُمْ إِلَٰهٌ وَٰحِدٌ فَٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ قُلُوبُهُم مُّنكِرَةٌ وَهُم مُّسْتَكْبِرُونَYour god is one God. But those who do not believe in the Hereafter - their hearts are disapproving, and they are arrogant.
