The chapter's response to these objection is a mix of "argument, threat, promise and reproach". It defends the Quran's divine origin, not a fabrication of Muhammad's, and says that Muhammad could not change it even if he wanted to. As for the challenge to bring God's punishment, the chapter says that God may defer punishment in this world if he wants to. It also tells of the punishment against unbelievers in the past, such as the people of Noah and Moses. It says that if the pagans waited for the punishment before believing, it would be too late, as was the case with the Pharaoh of Moses. According to the Quran, the Pharaoh only believed in God just before drowning, and that belief was too late and did not benefit him.
