Quran 7, Al-A'raf (The Heights) ⓘ

7:149And when they feared the consequences thereof and saw that they had gone astray, they said: Unless our Lord have mercy on us and forgive us, we verily are of the lost.

وَلَمَّا سُقِطَ فِي أَيْدِيهِمْ وَرَأَوْا أَنَّهُمْ قَدْ ضَلُّوا قَالُوا لَئِنْ لَمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ
