Regret and despair

مُّهْطِعِينَ إِلَى ٱلدَّاعِ ۖ يَقُولُ ٱلْكَـٰفِرُونَ هَـٰذَا يَوْمٌ عَسِرٌ

Racing ahead toward the Caller. The disbelievers will say, "This is a difficult Day."

وَأَمَّا مَنْ أُوتِىَ كِتَـٰبَهُۥ بِشِمَالِهِۦ فَيَقُولُ يَـٰلَيْتَنِى لَمْ أُوتَ كِتَـٰبِيَهْ

But as for he who is given his record in his left hand, he will say, "Oh, I wish I had not been given my record

يَـٰلَيْتَهَا كَانَتِ ٱلْقَاضِيَةَ

I wish it [i.e., my death] had been the decisive one.
