أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَعَلَىَّ إِجْرَامِى وَأَنَا۠ بَرِىٓءٌ مِّمَّا تُجْرِمُونَ
46:9.
Commentary:
The words, Say, If I have forged it, on me be my sin, refer to Noah and not to the Holy Prophet, and mean that God commanded Noah to tell his people that if in what he had said to them he had forged a lie against God, he would certainly be punished for it, so they need not worry about it. But if he was speaking the truth and was a true Messenger of God, then they had committed a great sin by rejecting him and would surely be called to account.
By saying, I am clear of the sins you commit, Noah clears himself of the charge of imposture in another way also. He points to his previous spotless life as proof of his truthfulness, for if he was free from the various sins in which his people were involved, he could not be expected to be so depraved as to forge lies against God, which was the most heinous of all sins.
46:9.
