لِّلَّهِ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۗ وَإِن تُبْدُوا۟ مَا فِىٓ أَنفُسِكُمْ أَوْ تُخْفُوهُ يُحَاسِبْكُم بِهِ ٱللَّهُ ۖ فَيَغْفِرُ لِمَن يَشَآءُ وَيُعَذِّبُ مَن يَشَآءُ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌ
Unto Allah (belongeth) whatsoever is in the heavens and whatsoever is in the earth; and whether ye make known what is in your minds or hide it, Allah will bring you to account for it. He will forgive whom He will and He will punish whom He will. Allah is Able to do all things.
