Yamadayev will be buried at a cemetery in the eastern Chechen city of Gudermes, where his brother Dzhabrail was laid to rest after he was killed in a terrorist attack in 2003.
The former member of the Russian parliament's lower house, the State Duma, was driving his Mercedes car in downtown Moscow on September 24 when he was attacked by unknown gunmen at 5:20 pm Moscow time (13:20 GMT). The attackers shot his car and then fled the scene in an Audi 80 car.
The former commandant of Chechnya Lt. Gen. Sergei Kizyun, who was riding in the car with Yamadayev, was seriously wounded and taken to a hospital.
A source in the emergency ward of the hospital said Kizyun had emergency surgery and as of Friday doctors said he was recovering from his wounds.
Police said it was obviously a contract killing as the perpetrators knew who was in the car, which they followed for some time before carrying out the attack.
The Russian Prosecutor General's Office has launched a criminal case on charges of murder and attempted murder.
