In Islamic jurisprudence, the term "haram" denotes anything that is explicitly prohibited by Allah in the Qur'an or by the Prophet Muhammad in the Hadiths. The opposite of haram is "halal," which signifies what is permissible. Between these two extremes, there exist actions that are "makruh" (discouraged but not sinful) and "mubah" (neutral).
The Basis for Determining Permissibility
To determine whether a cosmetic procedure like lip fillers is haram, scholars usually refer to a combination of sources: the Qur'an, Hadiths, and the consensus of scholars (ijma). They also consider the principles of Islamic jurisprudence (fiqh) and the objectives of Shariah (maqasid al-shariah), which aim to preserve religion, life, intellect, lineage, and property.
One of the primary arguments against lip fillers is that they constitute an alteration of Allah's creation. This argument is derived from several Qur'anic verses and Hadiths that caution against changing the natural form given by Allah. For instance, the Qur'an mentions that Satan will lead people to "change the creation of Allah" (Qur'an 4:119), which some scholars interpret as a prohibition against unnecessary cosmetic procedures.
