قَالَ رَبِّ إِنِّىٓ أَعُوذُ بِكَ أَنْ أَسْـَٔلَكَ مَا لَيْسَ لِى بِهِۦ عِلْمٌ ۖ وَإِلَّا تَغْفِرْ لِى وَتَرْحَمْنِىٓ أَكُن مِّنَ ٱلْخَـٰسِرِينَ Qur’an Hud (11:47)Qala rabbi innee aAAoothu bika an asalaka ma laysa lee bihi AAilmun wailla taghfir lee watarhamnee akun mina alkhasireena
Noah, in his natural affection and respect for ties of relationship, was overcome with human weakness in wishing to reverse the Decree of Allah. It was not sin but ignorance. His ignorance was corrected by divine inspiration, and he immediately saw the full Truth, acknowledged his error, and asked for Allah's forgiveness and mercy. This is the standard set for us all.
