وَذَرِ ٱلَّذِينَ ٱتَّخَذُوا۟ دِينَهُمْ لَعِبًۭا وَلَهْوًۭا وَغَرَّتْهُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا ۚ وَذَكِّرْ بِهِۦٓ أَن تُبْسَلَ نَفْسٌۢ بِمَا كَسَبَتْ لَيْسَ لَهَا مِن دُونِ ٱللَّهِ وَلِىٌّۭ وَلَا شَفِيعٌۭ وَإِن تَعْدِلْ كُلَّ عَدْلٍۢ لَّا يُؤْخَذْ مِنْهَآ ۗ أُو۟لَٰٓئِكَ ٱلَّذِينَ أُبْسِلُوا۟ بِمَا كَسَبُوا۟ ۖ لَهُمْ شَرَابٌۭ مِّنْ حَمِيمٍۢ وَعَذَابٌ أَلِيمٌۢ بِمَا كَانُوا۟ يَكْفُرُونَ
And forsake those who take their religion for a pastime and a jest, and whom the life of the world beguileth. Remind (mankind) hereby lest a soul be destroyed by what it earneth. It hath beside Allah no protecting ally nor intercessor, and though it offer every compensation it will not be accepted from it. Those are they who perish by their own deserts. For them is drink of boiling water and a painful doom, because they disbelieved.
Surah Al-An'aam(6:70)
