Quran 7:51 from Surah Al-A'raaf on Divine Marvels.
ٱلَّذِينَ ٱتَّخَذُواْ دِينَهُمۡ لَهۡوٗا وَلَعِبٗا وَغَرَّتۡهُمُ ٱلۡحَيَوٰةُ ٱلدُّنۡيَاۚ فَٱلۡيَوۡمَ نَنسَىٰهُمۡ كَمَا نَسُواْ لِقَآءَ يَوۡمِهِمۡ هَٰذَا وَمَا كَانُواْ بِـَٔايَٰتِنَا يَجۡحَدُونَ
English translation: Those who took their religion (as) an amusement and play and deluded them the life (of) the world So today We forget them as they forgot (the) meeting (of) their day this and [what] (as) they used to with Our Verses they reject
Transliteration: alladhina ittakhadhu dinahum lahwan wala'iban wagharrathumu al-hayatu al-dun'ya fal-yawma nansahum kama nasu liqaa yawmihim hadha wama kanu biayatina yajhaduna
