In traditional Islamic jurisprudence, Hudud (also Hadood, Hadud, Hudood, Arabic: حدود, romanized: ḥudūd pl., Hadd Arabic: حد sing.) literally "borders, boundaries, limits", refers to punishments (ranging from public lashing, public stoning to death, amputation of hands, crucifixion, depending on the crime), for several specific crimes (drinking alcohol, illicit sexual intercourse, false accusations of adultery, theft, apostasy from Islam, highway robbery, revolt against the ruler),for which punishments have been determined by verses of Quran or hadith.
Hudud is one of three categories of crime and punishment in classical Islamic literature, the other two being Qisas ("eye for an eye")–Diya (paying victims compensation), and Ta'zeer, (punishment left to the judge's or ruler's discretion). Hudud are crimes "against God", and cover the punishments given to those who exceed the "limits of God" (hududullah), associated with the Quran and in some cases inferred from hadith. (Qisas, Diya, and Ta'zeer deal with "crimes against man".)
