Sura Hūd 11:47

قَالَ رَبِّ إِنِّىٓ أَعُوذُ بِكَ أَنْ أَسْـَٔلَكَ مَا لَيْسَ لِى بِهِۦ عِلْمٌ وَإِلَّا تَغْفِرْ لِى وَتَرْحَمْنِىٓ أَكُن مِّنَ ٱلْخَٰسِرِينَ

qalā rabbi innī aʿūdhu bika an asʾalaka mā laysa lī bihi ʿilmun wa-illā taghfir lī wa-tarḥamnī akun mina l-khāsirīna

Noah said: "O my Lord! I do seek refuge with Thee, lest I ask Thee for that of which I have no knowledge. And unless thou forgive me and have Mercy on me, I should indeed be lost!"
