Piruz Nahavandi

"There were Persian children slaves in Madina. Seeing them, Piruz would say, You have been enslaved at such a tender age. This Omar sees eaten my heart. I will take his heart out. He made for himself a dagger with a very sharp edge and smeared it with poison."

"Omar then is reported to have asked Abu Lulu: "I heard that you make windmills; make one for me as well." In a sullen mood, Piruz said, Verily I will make such a mill for you, that the whole world would remember it."

"Abu Lu’lu’ah is a disbeliever, according to the consensus of the people of Islam. He was a Magi from among the worshipers of fire, so he killed Umar out of hatred for Islam and its people, out of love for the Magi, and in revenge for the infidels, for what Omar did to them when he conquered their lands, killed their leaders, and divided their money."

"Firuz was one of the greatest Muslims and Mujahideen of Islam, and was considered one of the most honest and truthful followers of Amir al-Mu'minin Ali Ibn Abi Talib. It is known that Abu Lulu was one of the best Shiites of Ali."
