Quran 39:25 from Surah Az-Zumar on Divine Marvels.
كَذَّبَ ٱلَّذِينَ مِن قَبۡلِهِمۡ فَأَتَىٰهُمُ ٱلۡعَذَابُ مِنۡ حَيۡثُ لَا يَشۡعُرُونَ
English translation: Denied those who (were) before them (were) before them so came upon them the punishment from where not they perceive
Transliteration: kadhaba alladhina min qablihim fa-atahumu al-'adhabu min haythu la yash'uruna
