Why do Muslims believe Ramadan should also be a time of fasting lust?

Muslims believe Ramadan should also be a time of fasting lust because lustful acts are believed to be under the influence of Shaytan, and ergo in error. The Qur’an states, “Satan threatens you with want, and orders you to commit shameful acts, but Allah promises his pardon and Grace”, which suggests Muslims who surrender to lustful temptation forget Allah words and follow Satan’s. Therefore Muslims believe they should fast lust to become masters of control, and prove to Allah they are faithful.
