Surah Al-A'raf, ayah 149

وَلَمَّا سُقِطَ فِيٓ أَيۡدِيهِمۡ وَرَأَوۡاْ أَنَّهُمۡ قَدۡ ضَلُّواْ قَالُواْ لَئِن لَّمۡ يَرۡحَمۡنَا رَبُّنَا وَيَغۡفِرۡ لَنَا لَنَكُونَنَّ مِنَ ٱلۡخَٰسِرِينَ ١٤٩

Walammā suqita fī aydīhim wara'aw annahum qad dallū qālū la il lam yarhamnā rabbunā wayaghfir lanā lanakūnanna minal-khāsirīn

And when regret overcame them⁴⁰⁶ 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."
