Surah Al-A'raf (The Heights), Verse 23

قَالَا رَبَّنَا ظَلَمْنَاۤ اَنْفُسَنَا وَاِنْ لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُوْنَنَّ مِنَ الْخٰسِرِیْنَ ۟

Qaalaa Rabbanaa zalamnaaa anfusanaa wa illam taghfir lanaa wa tarhamnaa lanakoonanna minal khaasireen

“They said: "Our Lord! We have wronged our own souls: If thou forgive us not and bestow not upon us Thy Mercy, we shall certainly be lost."”
