أَفَحَسِبْتُمْ أَنَّمَا خَلَقْنَاكُمْ عَبَثًا وَأَنَّكُمْ إِلَيْنَا لَا تُرْجَعُونَ ﴿١١٥﴾ فَتَعَالَى اللَّـهُ الْمَلِكُ الْحَقُّ ۖ لَا إِلَـٰهَ إِلَّا هُوَ رَبُّ الْعَرْشِ الْكَرِيمِ ﴿١١٦﴾ وَمَن يَدْعُ مَعَ اللَّـهِ إِلَـٰهًا آخَرَ لَا بُرْهَانَ لَهُ بِهِ فَإِنَّمَا حِسَابُهُ عِندَ رَبِّهِ ۚ إِنَّهُ لَا يُفْلِحُ الْكَافِرُونَ ﴿١١٧﴾ وَقُل رَّبِّ اغْفِرْ وَارْحَمْ وَأَنتَ خَيْرُ الرَّاحِمِينَ ﴿١١٨﴾

Wa man yad'u ma'allaahi ilaahan aakhara laa burhaana lahoo bihee fa-innamaa hisaabuhoo 'inda Rabbih; innahoo laa yuflihul-kaafiroon. Wa qul Rabbigh-fir warham wa Anta khairur-raahimeen.

(115) Then did you think that We created you uselessly and that to Us you would not be returned?" (116) So exalted is Allah, the Sovereign, the Truth; there is no deity except Him, Lord of the Noble Throne. (117) And whoever invokes besides Allah another deity for which he has no proof - then his account is only with his Lord. Indeed, the disbelievers will not succeed. (118) And, [O Muhammad], say, "My Lord, forgive and have mercy, and You are the best of the merciful."
