And fear the Day (of Resurrection) when no soul will be exchanged for another, nor will any intercession be accepted for the disbelievers, nor will they be set free in lieu of compensation nor will they be helped.

Indeed the believers (the Muslims) and those among the Jews, the Christians, and the Sabeans who sincerely accept faith in Allah and the Last Day* and do good deeds – their reward is with their Lord; and there shall be no fear upon them nor shall they grieve. (* i.e. convert to Islam)

These are the people who bought the worldly life in exchange of the Hereafter – so their punishment will not be lightened, nor will they be helped.

Do you not know that for Allah only is the kingship of the heavens and the earth? And except Allah, you have neither a protector nor any supporter?

And the People given the Book(s) said, “None will enter Paradise unless he is a Jew or a Christian”; these are their own imaginations; say (O dear Prophet Mohammed – peace and blessings be upon him), “Bring your proof, if you are truthful.”
