Quran 3:147 from Surah Aal-i-Imraan on Divine Marvels.
وَمَا كَانَ قَوۡلَهُمۡ إِلَّآ أَن قَالُواْ رَبَّنَا ٱغۡفِرۡ لَنَا ذُنُوبَنَا وَإِسۡرَافَنَا فِيٓ أَمۡرِنَا وَثَبِّتۡ أَقۡدَامَنَا وَٱنصُرۡنَا عَلَى ٱلۡقَوۡمِ ٱلۡكَٰفِرِينَ
English translation: And not were their words except that they said Our Lord forgive for us our sins and our excesses in our affairs and make firm our feet and give us victory against [the people] the disbelievers
Transliteration: wama kana qawlahum illa an qalu rabbana igh'fir lana dhunubana wa-is'rafana fi amrina wathabbit aqdamana wa-unsur'na ala al-qawmi al-kafirina
