The Repentance - 9:74
Although they speak words of disbelief and disbelieve after they have surrendered, they swear by Allah that they did not say them. In fact, they strived hard for what they could never attain. They sought revenge after Allah and His messenger had enriched them with His grace! It would be good for them if they repent. If they turn away, Allah will punish them with a painful torment in this world and in the Hereafter, and they will have neither friends nor helpers in the earth.
