Witchcraft is a capital offense in Saudi Arabia. Recently, another person was executed:
the Saudi Interior Ministry announced on Monday that it had beheaded a woman named Amina bint Abdul Halim bin Salem Nasser for practicing “witchcraft and sorcery.” The London-based al-Hayat newspaper, citing the chief of the religious police who arrested the woman after a report from a female investigator, claims Nasser was tricking people into paying $800 per session to have their illnesses cured.

How do prosecutors prove that someone is in fact a witch?
[T]he bar for proving someone guilty isn’t very high. Witch hunting is fairly institutionalized in Saudi Arabia, with the country’s religious police running an Anti-Witchcraft Unit and a sorcery hotline to combat practices like astrology and fortune telling that are considered un-Islamic.
But institutionalized is not the same thing as codified. A top official in the kingdom’s Ministry of Justice told Human Rights Watch in 2008 that there is no legal definition for witchcraft (Saudi Arabia doesn’t have a penal code) or specific body of evidence that has probative value in witchcraft trials.
Instead, judges have wide latitude in interpreting Sharia law and sentencing suspected criminals. And Amnesty International claims these judges use witchcraft charges to arbitrarily “punish people, generally after unfair trials, for exercising their right to freedom of speech or religion.” A Human Rights Watch researcher tells The Media Line that foreigners in particular are often the targets of sorcery accusations because of their traditional practices or, occasionally, because Saudi men facing charges of sexual harassment by domestic workers want to discredit their accusers.
The evidence arrayed against witchcraft suspects typically revolves around statements from accusers and suspicious personal belongings that suggest the supernatural, in a country where superstition is still widespread. (source)
Saudi authorities beheaded an Egyptian pharmacist who had been accused by neighbors of casting spells to separate a man from his wife and placing Korans in mosque bathrooms. “He confessed to adultery with a woman and desecrating the Koran by placing it in the bathroom,” the Saudi Press Agency reported, adding that books on black magic, a candle with an incantation “to summon devils,” and “foul-smelling herbs” had been found in the pharmacist’s home.
