Surah: 104 Al-Humaza
This is a Makki Surah and draws its name from the slanderers who are cursed, mentioned in the first verse.
Those who engage in slander and gossip assume that their wealth will always come to their aid, and they are always checking how much wealth they have, as they feel their possessions give them immense power.
In Surah An-Nur, Allaah (SWT) revealed that the punishment for those who slander chaste women are eighty lashes, and the rejection of their testimony in the future unless they repent.
For those who persist in such sins, they will be punished in the Fire from which they will not find any escape.
