وَكَذَٰلِكَ نَجۡزِي مَنۡ أَسۡرَفَ وَلَمۡ يُؤۡمِنۢ بِـَٔايَٰتِ رَبِّهِۦۚ وَلَعَذَابُ ٱلۡأٓخِرَةِ أَشَدُّ وَأَبۡقَىٰٓ
English translation: And thus We recompense (he) who transgresses and not believes in (the) Signs (of) his Lord And surely (the) punishment (of) the Hereafter (is) more severe and more lasting
Transliteration: wakadhalika najzi man asrafa walam yu'min biayati rabbihi wala'adhabu al-akhirati ashaddu wa-abqa
