Ash-Shura · 42:7

7. Just as I sent revelation to the prophets before you, O Messenger, I have revealed to you an Arabic Qur’ān so that you may warn Makkah and the Arab towns around it and thereafter the entire mankind, and warn people of the day of resurrection when Allah will gather the earlier ones and the later ones in one plain for reckoning and recompense. There is no doubt in the occurrence of that day, on which people will be divided into two groups: One group will be in Paradise, and these are the believers; and one group will be in the Fire, and these are the disbelievers.
