Remembrance of Allah (At-Tadhkir billah) in the Holy Quran

﴿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 ﴾ [Al-An‘ām: 70]

(70) And leave those who take their religion as amusement and diversion and whom the worldly life has deluded. But remind with the Qur'an, lest a soul be given up to destruction for what it earned; it will have other than Allah no protector and no intercessor. And if it should offer every compensation, it would not be taken from it. Those are the ones who are given to destruction for what they have earned. For them will be a drink of scalding water and a painful punishment because they used to disbelieve.
