Surat Al-A'raaf (The Heights) - الأعراف

وَلَمَّا سُقِطَ فِىٓ أَيْدِيهِمْ وَرَأَوْا۟ أَنَّهُمْ قَدْ ضَلُّوا۟ قَالُوا۟ لَئِن لَّمْ يَرْحَمْنَا رَبُّنَا وَيَغْفِرْ لَنَا لَنَكُونَنَّ مِنَ ٱلْخَٰسِرِينَ ﴿١٤٩﴾

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.
