Here is evidence that this verse of the Koran is not a relic of history, but something that Sharia adherents take seriously as instructions valid for all time:
"The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is: execution, or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter..." -- Koran 5:33
Sharia Alert from the Kingdom of Two Holy Places: "Saudi court upholds child rapist crucifixion ruling," from Reuters, November 3 (thanks to Block Ness):
RIYADH (Reuters) - A Saudi court of cassation upheld a ruling to behead and crucify a 22-year-old man convicted of raping five children and leaving one of them to die in the desert, newspapers reported on Tuesday....International rights groups have accused the kingdom, the birthplace of Islam, of applying draconian justice, beheading murderers, rapists and drug traffickers in public. So far this year about 40 people have been executed in Saudi Arabia.
In Saudi Arabia, crucifixion means tying the body of the convict to wooden beams to be displayed to the public after beheading.
