الاعراف — Al-A'raf Ayat 149
وَلَمَّا سُقِطَ فِيْٓ اَيْدِيْهِمْ وَرَاَوْا اَنَّهُمْ قَدْ ضَلُّوْاۙ قَالُوْا لَىِٕنْ لَّمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُوْنَنَّ مِنَ الْخٰسِرِيْنَ
Wa lammā suqiṭa fī aidīhim wa ra'au annahum qad ḍallū, qālū la'il lam yarḥamnā rabbunā wa yagfir lanā lanakūnanna minal-khāsirīn(a).
"And when regret overcame them and they saw that they had gone astray, they said, "If our Lord does not have mercy upon us and forgive us, we will surely be among the losers.""
