Paradise, as described in many verses of Quran, is a place of eternal bliss and it is promised to believers. God shows his mercy to the believers by rewarding them with Paradise. Whoever denies God or worships something with, or instead of Him, or claims that God has a son or daughter or partner, will be doomed in the Hereafter to the hellfire. Converting to Islam will save a person from the torment of the grave, suffering on the Day of Judgement and eternal hellfire. Embracing Islam saves a person from the eternal Hellfire that all the prophets warned their followers about.
