O you who believe! it is binding on those whom your right hands possess (domestic servants) and those (of your children) who have not reached the age of puberty to ask your permission (before coming into your private rooms) in three instances, before the morning Prayer, and when you lay aside your clothes due to the heat (in summer) at noon and after the night Prayer. These are three times when your privacy should be respected. At other times no blame shall lie on you or on them (if they come to you without permission), for they have to move about (waiting upon you) some of you (attending) upon others (according to need). That is how Allâh explains to you His commandments, for Allâh is All-Knowing, All-Wise. - Quran 24:58
