Quran 6:70 from Surah Al-An'aam on Divine Marvels.
وَذَرِ ٱلَّذِينَ ٱتَّخَذُواْ دِينَهُمۡ لَعِبٗا وَلَهۡوٗا وَغَرَّتۡهُمُ ٱلۡحَيَوٰةُ ٱلدُّنۡيَاۚ وَذَكِّرۡ بِهِۦٓ أَن تُبۡسَلَ نَفۡسُۢ بِمَا كَسَبَتۡ لَيۡسَ لَهَا مِن دُونِ ٱللَّهِ وَلِيّٞ وَلَا شَفِيعٞ وَإِن تَعۡدِلۡ كُلَّ عَدۡلٖ لَّا يُؤۡخَذۡ مِنۡهَآۗ أُوْلَٰٓئِكَ ٱلَّذِينَ أُبۡسِلُواْ بِمَا كَسَبُواْۖ لَهُمۡ شَرَابٞ مِّنۡ حَمِيمٖ وَعَذَابٌ أَلِيمُۢ بِمَا كَانُواْ يَكۡفُرُونَ
English translation: And leave those who take their religion (as) a play and amusement and deluded them the life (of) the world But remind with it lest is given up to destruction a soul for what it (has) earned not (is) for it from besides Allah any protector and not any intercessor And if it offers ransom every ransom not will it be taken from it Those (are) ones who are given to destruction for what they earned For them (will be) a drink of boiling water and a punishment painful because they used to disbelieve
