Bombing Curse

The Bombing Curse (also known as the curse of the terrorist's dream), is a curse to cause a violent explosion. This is a curse commonly used by Death Eaters to break into highly secured areas, such as Gringotts Wizarding Bank. It may also be known to be used during the Battle of Hogwarts (on 2 May, 1998), which resulted in the death of Fred Weasley.

Sometimes, fire can be seen and in some instances, green smoke clouds appear from the curses' effects.

Dumbledore describes this curse as "highly dangerous" and like fiendfyre, one must know the effects and any counter-curses before performed it, as it kills anyone in path, giving it less than a minute unless, like Basilisk Venom, a phoenix comes in and produces tears."I then disappear at the right time and re-appeared behind them and casted one violent explosion, yelling “Allahu Akbar!” as I flicked my wand, causing a huge explosion, killing several Death Eaters, including Adölfissen Russon."

Etymology

 * The incantation is derived from the Arabic الله أكبر, meaning "God is Great", normally used by Muslims in the Islamic Culture in thanksgiving and adoration, derived from terrorists used as a battle cry before an explosion, typically.
