Quran 24:59 — Light (Al-Noor)

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.

[24:58] 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.

[24:60] The elderly women who do not expect to get married commit nothing wrong by relaxing their dress code, provided they do not reveal too much of their bodies. To maintain modesty is better for them. GOD is Hearer, Knower.
