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

“Said [Noah]: "O my Sustainer! Verily, I seek refuge with Thee from [ever again] asking of Thee anything whereof I cannot have any knowledge! For unless Thou grant me forgiveness and bestow Thy mercy upon me, I shall be among the lost!"”

Mentioned in the third verse (47) is the apology tendered by Sayyidna Nuh (علیہ السلام) . In gist, it is a return to Allah in submission and entreaty, a prayer for the protection of Allah, His forgiveness for past omissions, and a request for His mercy. From here we learn that, should one commit a mistake, let him not rely on his personal resolve to stay safe from it in the future. He should, rather, seek the protection of Allah Ta` ala and pray to Him that He is the One who can keep him safe from errors and sins.
