Al An'am, 31 Ayah
6:31
قَدۡ 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 Khasira Al-Ladhīna Kadhdhabū Biliqā'i Al-Lahi ۖ Ĥattá 'Idhā Jā'at/humu As-Sā`atu Baghtatan Qālū Yā Ĥasratanā `Alá Mā Farraţnā Fīhā Wa Hum Yaĥmilūna 'Awzārahum `Alá Žuhūrihim ۚ 'Alā Sā'a Mā Yazirūna
Those will have lost who deny the meeting with Allah, 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," while they bear their burdens on their backs. Unquestionably, evil is that which they bear.
