What is belief in the hereafter? Believe in the hereafter…
The Last Day (Qiyamah, Day of Judgment or Resurrection) will come, at which time life in this world will end and the hereafter will start. People will resurrect after their deaths and will be held accountable for what they did in this world. Believers will go to Paradise and disbelievers will go to Hell.
Those who believed but committed sins will either go to Paradise after a punishment commensurate with their sins or, if they are granted Allah’s forgiveness, will go directly to Paradise
