Thus does Allah make clear the revelations for you; and Allah is All-Knowing, All-Wise." Commentary: Faithful parents are responsible for teaching Divine religious ordinances to their children. The place where parents habitually sleep must be separate and far from the sight of the children, otherwise, there was no need for taking permission, as man must allocate some hours for his wife during 24 hours and issues must not disturb them.
Islam is a religion for life and it is completely comprehensive. It has programs and plans for both common trivial issues such as entrance of children in parent's room (mentioned in this verse) and important matters such as the establishment of universal government. Anyway, as we said before, the most important issue that is comprehensively discussed in this Sura is the matter of public chastity and righting against any sexual deviation.
This verse also is about one of these affairs that relate this issue and it explains its characteristics; the matter is concerned to the mature and immature issues' taking permission when they want to enter the room which belongs to their parents. At first, it says: "O you who believe!
Do let those whom your right hands possess, and those of you who have not reached to puberty, ask permission of you at three times (for coming into your room): before the morning prayer, and at midday when you put off your clothes, and after the night prayer. ..." As Raqib says in his book, Mufradat, and Firuz'abadi in Qamus, the Arabic word /zahirat/ means midday and about noontime when people take off their outer clothes and man and wife may be together privately. "...
(These are) three times of privacy for you...." The Arabic word /'aurat/ originally is derived from the word /'ar/ meaning shame and fault. Since showing genital organs is the cause of fault and shame, in Arabic language it is called /'aurat/. Sometimes the word /'aurat/ is also used to mean an opening and cut in wall and dress and the like. Sometimes it means absolutely fault.
Anyway, using this word for these three times is for the matter that people do not compel themselves to be veiled fully as in other times they do and they consider these times their privacy. It is obvious that this command only involves parents who must force their issues to do this, for children have not come of age yet so that they are not obligated to carry out divine duties, therefore parents are addressed here.
