Syedna Ibn Abbas (may Allah be pleased with them) narrates that during a battle, cheese was presented before the Noble Prophet (peace and blessings be upon him). He (peace be upon him) asked: "Where was this prepared?" They said: "It was prepared in the region of Persia, and we think that carrion meat is added to it." He (peace be upon him) said: "Cut it with a knife and eat it after reciting Bismillah." The second time when Shareek narrated this, he added: "People began to cut it with the sharp edge of their staffs."
