It is claimed that humans have to be cleansed of sin before being allowed into the presence of God after death. Those who are not cleansed are said to be forever deprived of that joy.
وهنالك مَن يعتقد ان على البشر التطهُّر من خطاياهم حتى يُسمَح لهم بالمثول امام الله ،‏ ومَن لا يتطهَّرون يُحرَمون الى الابد من هذا النعيم .‏
