Quran 24:58 — Light (Al-Noor)

O you who believe, permission must be requested by your servants and the children who have not attained puberty (before entering your rooms). This is to be done in three instances—before the Dawn Prayer, at noon when you change your clothes to rest, and after the Night Prayer. These are three private times for you. At other times, it is not wrong for you or them to mingle with one another. GOD thus clarifies the revelations for you. GOD is Omniscient, Most Wise.

[24:57] Do not think that those who disbelieve will ever get away with it. Their final abode is Hell; what a miserable destiny.

[24:59] Once the children reach puberty, they must ask permission (before entering) like those who became adults before them have asked permission (before entering). GOD thus clarifies His revelations for you. GOD is Omniscient, Most Wise.
