The Islamic supremacists in Mali are characterized as "extremists," but what they are doing here is strictly Qur'anic:
"This is the recompense of those who fight against God and His Messenger, and hasten about the earth, to do corruption there: they shall be slaughtered, or crucified, or their hands and feet shall alternately be struck off; or they shall be banished from the land. That is a degradation for them in this world; and in the world to come awaits them a mighty chastisement" -- Qur'an 5:33
"And the thief, male and female: cut off the hands of both, as a recompense for what they have earned, and a punishment exemplary from God; God is All-mighty, All-wise." -- Qur'an 5:38
"Islamists hack off hand of 1 more robber in Mali," from AP, September 18 (thanks to Kenneth):
BAMAKO, Mali (AP) -- A spokesman for one of the radical Islamist groups controlling northern Mali says their fighters have cut off a thief's hand in the former tourist hotspot of Timbuktu.
Oumar Ould Hamaha told The Associated Press the robber had been caught after breaking into a store, from where he had stolen merchandise worth $2,000. His hand was cut off Sunday afternoon.
It was at least the seventh amputation carried out by the Islamists since they seized control of the territory in April. It comes after last Monday's gruesome double amputation of five highway robbers in the northern city of Gao. According to the strict form of Shariah practiced by the rebels, armed robbery requires the cutting off of both a hand and a foot.
That's not a "strict form of Sharia," that's a Qur'anic imperative. See Qur'an 5:38 above.
