Surah Al-A'raf, Verse 149

وَلَمَّا سُقِطَ فِيٓ أَيۡدِيهِمۡ وَرَأَوۡاْ أَنَّهُمۡ قَدۡ ضَلُّواْ قَالُواْ لَئِن لَّمۡ يَرۡحَمۡنَا رَبُّنَا وَيَغۡفِرۡ لَنَا لَنَكُونَنَّ مِنَ ٱلۡخَٰسِرِينَ١٤٩

walammā suqiṭa fī aydīhim wara-aw annahum qad ḍallū qālū la-in lam yarḥamnā rabbunā wayaghfir lanā lanakūnanna mina l-khāsirīna

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."
