Quran 34:9 from Surah Saba on Divine Marvels.
أَفَلَمۡ يَرَوۡاْ إِلَىٰ مَا بَيۡنَ أَيۡدِيهِمۡ وَمَا خَلۡفَهُم مِّنَ ٱلسَّمَآءِ وَٱلۡأَرۡضِۚ إِن نَّشَأۡ نَخۡسِفۡ بِهِمُ ٱلۡأَرۡضَ أَوۡ نُسۡقِطۡ عَلَيۡهِمۡ كِسَفٗا مِّنَ ٱلسَّمَآءِۚ إِنَّ فِي ذَٰلِكَ لَأٓيَةٗ لِّكُلِّ عَبۡدٖ مُّنِيبٖ
English translation: Then, do not they see towards what (is) before them (is) before them and what (is) behind them of the heaven and the earth If We will We (could) cause to swallow them We (could) cause to swallow them the earth or cause to fall upon them fragments from the sky Indeed in that surely, is a Sign for every slave who turns (to Allah)
Transliteration: afalam yaraw ila ma bayna aydihim wama khalfahum mina al-samai wal-ardi in nasha nakhsif bihimu al-arda aw nus'qit alayhim kisafan mina al-samai inna fi dhalika laayatan likulli abdin munibin
