Narrated Kab ibn Malik: When the Prophet صلی اللہ علیہ وسلم intended to go on an expedition, he always pretended to be going somewhere else, and he would say: War is deception. Abu Dawud said: Only Mamar has transmitted this tradition. By this he refers to his statement "War is deception" through this chain of narrators. He narrated it from the tradition of Amr bin Dinar from Jabir, and from the tradition of Mamar from Hammam bin Munabbih on the authority of Abu Hurairah.
