In using deception to lure Rabbani to his death, this Muslim was imitating Muhammad, the prophet of Islam, who once took offense to Ka'b bin Al-Ashraf, a poet who had mocked him, and asked his followers: "Who is willing to kill Ka'b bin Al-Ashraf who has hurt Allah and His Apostle?" One of the Muslims, Muhammad bin Maslama answered, "O Allah's Apostle! Would you like that I kill him?" When Muhammad said that he would, Muhammad bin Maslama said, "Then allow me to say a (false) thing (i.e. to deceive Kab)." Muhammad responded: "You may say it." Muhammad bin Maslama duly lied to Ka'b, luring him into his trap, and murdered him. (Bukhari, volume 5, book 59, number 369)

Of course, Muhammad also famously said, "War is deceit."

More on this story. War Is Deceit Update: "Afghan president: Rabbani's killer staged a ruse," by Amir Shah and Deb Reichmann for the Associated Press, September 22 (thanks to Bill):

KABUL, Afghanistan—The suicide bomber who killed Afghanistan's former president, Burhanuddin Rabbani​, gained access to him by presenting officials beforehand with an audio recording of a purported Taliban peace offer, President Hamid Karzai said Thursday....

The assassin, who hid a bomb in his turban, killed the 70-year-old former Afghan leader Tuesday at his home in Kabul.

[....] Rabbani's death "raises very serious questions" as to whether the Taliban and those who support them have any real interest in reconciling with the Afghan government.

No kidding, really?"
