Angels (ملائكة‎‎) are heavenly beings mentioned many times in the Qur'an and hadith literature. Unlike humans or jinn, they have no biological needs and therefore no lower desires predicated by animal nature; consequently, they may be described as creatures of pure emotion, who though endowed with free will are not subject to temptation. This make Angels beings who are composed of light and are in essence consisting of motion of the universe and emotions. While it has been said that angels lack free will since they are known from the Qur'an to strictly obey what God commands due the lack of rational decision-making because of lack of lower desires seen in nature. This assertion leads to scopes of interpretation amongst different schools of Islam amongst the extent of free will which angels have not as beings of endowed with human reason but as beings of emotions.
