Quran Al-A'raf 7:149
وَلَمَّا سُقِطَ فِيٓ أَيۡدِيهِمۡ وَرَأَوۡاْ أَنَّهُمۡ قَدۡ ضَلُّواْ قَالُواْ لَئِن لَّمۡ يَرۡحَمۡنَا رَبُّنَا وَيَغۡفِرۡ لَنَا لَنَكُونَنَّ مِنَ ٱلۡخَٰسِرِينَ ١٤٩
Translation
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."
