Quran 69:25 from Surah Al-Haaqqa on Divine Marvels.
وَأَمَّا مَنۡ أُوتِيَ كِتَٰبَهُۥ بِشِمَالِهِۦ فَيَقُولُ يَٰلَيۡتَنِي لَمۡ أُوتَ كِتَٰبِيَهۡ
English translation: But as for (him) who is given his record in his left hand will say O! I wish not I had been given my record
Transliteration: wa-amma man utiya kitabahu bishimalihi fayaqulu yalaytani lam uta kitabiyah
