Qabasقَدۡ خَسِرَ ٱلَّذِينَ كَذَّبُواْ بِلِقَآءِ ٱللَّهِۖ حَتَّىٰٓ إِذَا جَآءَتۡهُمُ ٱلسَّاعَةُ بَغۡتَةٗ قَالُواْ يَٰحَسۡرَتَنَا عَلَىٰ مَا فَرَّطۡنَا فِيهَا وَهُمۡ يَحۡمِلُونَ أَوۡزَارَهُمۡ عَلَىٰ ظُهُورِهِمۡۚ أَلَا سَآءَ مَا يَزِرُونَ ٣١
Qad khasiral-ladhīna kaddhabū biliqā'illāhi hattā idhā jā'athumus-sā'atu baghtatan qālū yāhasratanā 'alā mā farratnā fīhā wahum yahmilūna awzārahum 'alā zuhūrihim alā sā'a mā yazirūn
Those will have lost who deny the meeting with Allāh, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it [i.e., the Hour]," while they bear their burdens [i.e., sins] on their backs. Unquestionably, evil is that which they bear.
