Did ibn hazm say its permissible to kill blind and crippled men in war?

I was sent this quote by a friend: >It is permissible to kill anyone other than those we mentioned above of the Polytheists, both the combatant and noncombatant, the businessman and employee, the elderly man whether or not he be a person of influence the farmer, the bishop or priest or monk, the blind or crippled, no one is given exception
(Muhalla) and it was attributed to his Muhalla. However it is a very big book and I cant read arabic. Is it true Ibn Hazm said this??
