وَلَمَّا سُقِطَ فِىٓ أَيْدِيهِمْ وَرَأَوْا۟ أَنَّهُمْ قَدْ ضَلُّوا۟ قَالُوا۟ لَئِن لَّمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُونَنَّ مِنَ ٱلْخَـٰسِرِينَ ۝١٤٩

7:149 And 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.
