Sura al-Aʿrāf 7:149

وَلَمَّا سُقِطَ فِىٓ أَيْدِيهِمْ وَرَأَوْا۟ أَنَّهُمْ قَدْ ضَلُّوا۟ قَالُوا۟ لَئِن لَّمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُونَنَّ مِنَ ٱلْخَٰسِرِينَ

wa-lammā suqiṭa fī aydīhim wa-raʾaw annahum qad ḍallū qālū lain lam yarḥamnā rabbunā wa-yaghfir la-nā la-nakūnanna mina l-khāsirīna

When they repented, and saw that they had erred, they said: "If our Lord have not mercy upon us and forgive us, we shall indeed be of those who perish."
