Surah Saba' (The Sheba), Verse 9

اَفَلَمْ یَرَوْا اِلٰی مَا بَیْنَ اَیْدِیْهِمْ وَمَا خَلْفَهُمْ مِّنَ السَّمَآءِ وَالْاَرْضِ اِنْ نَّشَاْ نَخْسِفْ بِهِمُ الْاَرْضَ اَوْ نُسْقِطْ عَلَیْهِمْ كِسَفًا مِّنَ السَّمَآءِ اِنَّ فِیْ ذٰلِكَ لَاٰیَةً لِّكُلِّ عَبْدٍ مُّنِیْبٍ 

Afalam yaraw ilaa maa baina aydeehim wa maa khalfahum minas samaaa'i wal ard; in nashad nakhsif bihimul arda aw nusqit 'alaihim kisafam minas samaaa'; inna fee zaalika la Aayatal likulli 'abdim muneeb

“See they not what is before them and behind them, of the sky and the earth? If We wished, We could cause the earth to swallow them up, or cause a piece of the sky to fall upon them. Verily in this is a Sign for every devotee that turns to Allah (in repentance).”
