Translation:

47. 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!"

Notes (Tafseer)

1541. 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.
