Surat Al-'An`ām - سورة الأنعام

قَدْ خَسِرَ الَّذِينَ كَذَّبُوا بِلِقَاءِ اللَّهِ ۖ حَتَّىٰ إِذَا جَاءَتْهُمُ السَّاعَةُ بَغْتَةً قَالُوا يَا حَسْرَتَنَا عَلَىٰ مَا فَرَّطْنَا فِيهَا وَهُمْ يَحْمِلُونَ أَوْزَارَهُمْ عَلَىٰ ظُهُورِهِمْ ۚ أَلَا سَاءَ مَا يَزِرُونَ

Muhsin Khan: They indeed are losers who denied their Meeting with Allah, until all of a sudden, the Hour (signs of death) is on them, and they say: "Alas for us that we gave no thought to it," while they will bear their burdens on their backs; and evil indeed are the burdens that they will bear!
