(431) (The warner) said: "Even if I bring you better guidance than that which you found your fathers following?" They said: "Verily, we disbelieve in that with which you have been sent."

(432) And when the truth (this Qur'an) came to them, they (the disbelievers in this Qur'an) said: "This is magic, and we disbelieve therein."

(434) Verily, the Mujrimun (criminals, sinners, disbelievers) will be in the torment of Hell to abide therein forever.

(435) We sent it (this Qur'an) down on a blessed night [(i.e. night of Al-Qadr, Surah No. 97) in the month of Ramadan - the 9th month of the Islamic calendar].

(439) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).

(440) And to Allah belongs the kingdom of the heavens and the earth. And on the Day that the Hour will be established - on that Day the followers of falsehood (polytheists, disbelievers, worshippers of false deities) shall lose (everything).
