In linguistic terms, Sharia refers to a water source, which is the source to which people who want to drink come, so they drink from it and fill their buckets, and perhaps bring their animals to drink from it as well.
The Arabs do not call a water source Sharia unless the water is flowing without interruption, and is visible and can be seen.
In Sharia terminology, Shariah refers to the entire religion (Islam), which Allah has chosen for His slaves to bring them forth thereby from the depths of darkness into the light. It is what He has prescribed for them and what He has explained to them of commands and prohibitions, halal (lawful) and haram (unlawful).
Whoever follows the Sharia of Allah, regarding as permissible (halal) that which He has permitted and regarding as forbidden (haram) that which He has prohibited, will triumph.
Whoever goes against the Sharia (laws) of Allah has exposed himself to divine vengeance, wrath and punishment.
Allah, may He be exalted, says in the Quran (interpretation of the meaning):
“Then We put you, [O Muhammad], on an ordained way [Sharia] concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know” (Quran 45:18)
Due to Islamophobia and the false reports in the media, Sharia has been referred exclusively to the penal code yet the penal code only makes up around 15% of Sharia law.
Sharia deals with many topics, including crime, politics, and economics, as well as personal matters such as sexual intercourse, hygiene, diet, prayer, everyday etiquette and fasting. Adherence to Sharia has served as one of the distinguishing characteristics of Islam. In short, Sharia is the infallible law of God.
