“The Koran is very specific with regard to the nature of human struggle, because in order for a human to be at peace with himself, they must control their baser instincts,” The quest to control base instincts such as greed, lust, and cruelty and to seek spiritual purity is known by Muslims as the “great jihad.” Featured widely in the Koran, the “great jihad” is a person’s most important internal struggle.  (Imam Sulayman S Nyang).
