Mohammad Sidique Khan's Prayer Rug

Origin
Mohammad Sidique Khan (20 October 1974 – 7 July 2005) was the oldest of the four homegrown suicide bombers and believed to be the leader responsible for the 7 July 2005 London bombings, in which bombs were detonated on three London Underground trains and one bus in central London suicide attacks, killing 56 people including the attackers and injured over 700. Khan bombed the Edgware Road train killing himself and six other people.

Effect
When someone prays on the rug, they will be compelled to act violently. The longer one uses the rug, the more severe the violence they will cause.
