Quran 6:31 Al-An'am, ayah 31 of 165

قَدْ خَسِرَ ٱلَّذِينَ كَذَّبُوا۟ بِلِقَآءِ ٱللَّهِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمُ ٱلسَّاعَةُ بَغْتَةً قَالُوا۟ يَـٰحَسْرَتَنَا عَلَىٰ مَا فَرَّطْنَا فِيهَا وَهُمْ يَحْمِلُونَ أَوْزَارَهُمْ عَلَىٰ ظُهُورِهِمْ ۚ أَلَا سَآءَ مَا يَزِرُونَ ۝٣١

6:31 They indeed are losers who deny their meeting with Allah until, when the Hour cometh on them suddenly, they cry: Alas for us, that we neglected it! They bear upon their backs their burdens. Ah, evil is that which they bear!
