All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
There is nothing wrong with washing chicken eggs before cooking them for hygienic reasons so as to avoid anything that may be unclean, yet it is not obligatory. The discharge that covers chicken eggs is clean according to the majority of scholars, especially from chickens that were fed on pure fodder; since it is from a pure and eatable animal.
The Maaliki scholar Ibn Farhoon said: “Eggs should be washed before breaking, but if they are not washed there is no harm.” In fact, eggs should be washed because of the possibility that they might be from hens whose fodder is impure. Jurists label such animals as “Jallaalah”; i.e. any animal fed on impurities. Held
Allaah Knows best.
