Imam Sadiq (a.s) said the following regarding the Almighty God's statement: “O' ye who believe! Let those whom your right hands possess, and the (children) among you who have not come of age ask you permission (before they come to your presence), on three occasions” [The Holy Quran: Nur 24:58] “This refers to the male or female servants or young children who have not reached puberty. They should seek permission to enter on three occasions: After the night prayer which is the time to sleep, and “the while ye doff your clothes for the noon day heat” and “before morning prayer.” Your servants need not ask for permission to enter at other times.”
