Quran 14:43 from Surah Ibrahim on Divine Marvels.
مُهۡطِعِينَ مُقۡنِعِي رُءُوسِهِمۡ لَا يَرۡتَدُّ إِلَيۡهِمۡ طَرۡفُهُمۡۖ وَأَفۡـِٔدَتُهُمۡ هَوَآءٞ
English translation: Racing ahead raised up their heads not returning towards them their gaze and their hearts (are) empty
Transliteration: muh'ti'ina muq'ni'i ruusihim la yartaddu ilayhim tarfuhum wa-afidatuhum hawaon
