(And remember) the Day when He will gather you (all) on the Day of Gathering, that will be the Day of mutual loss and gain (i.e. loss for the disbelievers as they will enter the Hell-fire and gain for the believers as they will enter Paradise). And whosoever believes in Allah and performs righteous good deeds, He will remit from him his sins, and will admit him to Gardens under which rivers flow (Paradise) to dwell therein forever, that will be the great success.

But those who disbelieved (in the Oneness of Allah - Islamic Monotheism) and denied Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination.
