Quran 9:126 from Surah At-Tawba on Divine Marvels.
أَوَلَا يَرَوۡنَ أَنَّهُمۡ يُفۡتَنُونَ فِي كُلِّ عَامٖ مَّرَّةً أَوۡ مَرَّتَيۡنِ ثُمَّ لَا يَتُوبُونَ وَلَا هُمۡ يَذَّكَّرُونَ
English translation: Do not they see that they are tried [in] every year once or twice Yet not they turn (in repentance) and not they pay heed
Transliteration: awala yarawna annahum yuf'tanuna fi kulli amin marratan aw marratayni thumma la yatubuna wala hum yadhakkaruna
