Surah An-Nahl — Ayah 22 (16:22)
إِلَٰهُكُمۡ إِلَٰهٞ وَٰحِدٞۚ فَٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱلۡأٓخِرَةِ قُلُوبُهُم مُّنكِرَةٞ وَهُم مُّسۡتَكۡبِرُونَ ٢٢
English translation (Saheeh International)
Your god is one God. But those who do not believe in the Hereafter - their hearts are disapproving, and they are arrogant.
Brief commentary
The only being that truly deserves to be worshipped is only one being who has no partner and that is Allah. Those who deny the resurrection and the recompense, their hearts are arrogant and they do not fear the reckoning. They therefore do not believe that there will be any reckoning or retribution. They are arrogant and refuse to accept the truth.
