Quran 50:37 from Surah Qaaf on Divine Marvels.
إِنَّ فِي ذَٰلِكَ لَذِكۡرَىٰ لِمَن كَانَ لَهُۥ قَلۡبٌ أَوۡ أَلۡقَى ٱلسَّمۡعَ وَهُوَ شَهِيدٞ
English translation: Indeed in that surely, is a reminder for (one) who is for him a heart or (who) gives ear (who) gives ear while he (is) a witness
Transliteration: inna fi dhalika ladhik'ra liman kana lahu qalbun aw alqa al-sam'a wahuwa shahidun
