Al-A'raf - 7:149

وَلَمَّا سُقِطَ فَي أَيْدِيهِمْ وَرَأَوْاْ أَنَّهُمْ قَدْ ضَلُّواْ قَالُواْ لَئِن لَّمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُونَنَّ مِنَ الْخَاسِرِينَ
[7:149]
And when they repented and saw that they had gone astray, they said: If our Lord show not mercy to us and forgive us we shall certainly be of the losers.
When they repented, and saw that they had erred, they said: "If our Lord have not mercy upon us and forgive us, we shall indeed be of those who perish."
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.
