Quran 16:22 from Surah An-Nahl on Divine Marvels.
إِلَٰهُكُمۡ إِلَٰهٞ وَٰحِدٞۚ فَٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱلۡأٓخِرَةِ قُلُوبُهُم مُّنكِرَةٞ وَهُم مُّسۡتَكۡبِرُونَ
English translation: Your god (is) God One But those who (do) not believe in the Hereafter their hearts refuse and they (are) arrogant
Transliteration: ilahukum ilahun wahidun fa-alladhina la yu'minuna bil-akhirati qulubuhum munkiratun wahum mus'takbiruna
