Surat Saba' - سورة سبأ

أَفَلَمْ يَرَوْا إِلَىٰ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُم مِّنَ السَّمَاءِ وَالْأَرْضِ ۚ إِن نَّشَأْ نَخْسِفْ بِهِمُ الْأَرْضَ أَوْ نُسْقِطْ عَلَيْهِمْ كِسَفًا مِّنَ السَّمَاءِ ۚ إِنَّ فِي ذَٰلِكَ لَآيَةً لِّكُلِّ عَبْدٍ مُّنِيبٍ

Muhsin Khan: See they not what is before them and what is behind them, of the heaven and the earth? If We will, We shall sink the earth with them, or cause a piece of the heaven to fall upon them. Verily, in this is a sign for every faithful believer that [believes in the Oneness of Allah], and turns to Allah (in all affairs with humility and in repentance).
