What Does Akhirah Mean?
Akhirah refers to the afterlife, the life that Muslims believe all humans will experience after death. Muslims believe that every soul will either live a life of eternity in Heaven or in Hell, depending on the weight of their good deeds versus their sins on the Day of Judgment.
Those people that spent their lives being righteous and worshiping Allah (SWT) will get to live for all of eternity in Paradise (ie. Jannah). The people that spent their lives disobeying Allah (SWT) will spend the rest of eternity in Hell (ie. Jahanam). The one to judge who will go to Heaven or Hell will be Allah (SWT).
