Al-A'raf - 7:51

الَّذِينَ اتَّخَذُواْ دِينَهُمْ لَهْوًا وَلَعِبًا وَغَرَّتْهُمُ الْحَيَاةُ الدُّنْيَا فَالْيَوْمَ نَنسَاهُمْ كَمَا نَسُواْ لِقَاء يَوْمِهِمْ هَـذَا وَمَا كَانُواْ بِآيَاتِنَا يَجْحَدُونَ
[7:51]
Who take their religion for an idle sport and a play and this life's world deceives them; so today We forsake them, as they neglected the meeting of this day of theirs and as they denied Our communications.
"Such as took their religion to be mere amusement and play, and were deceived by the life of the world." That day shall We forget them as they forgot the meeting of this day of theirs, and as they were wont to reject Our signs.
Who took their religion for a sport and pastime, and whom the life of the world beguiled. So this day We have forgotten them even as they forgot the meeting of this their Day and as they used to deny Our tokens.
