Qada'' is the Arabic word for Decree. They may or may not be used interchangeably depending on the context. Essentially, Destiny is what Allah has decreed. Allah has knowledge of everything in His creation. Nothing occurs except by His will. Human beings are given free will, and it must be made clear that destiny does not have a cause-and-effect influence of the choices humans make. The choices that humans make are all within Allah''s knowledge.
