Chapter 4 [Surah An Nissa] : Verse 34.
” Men are the protectors and maintainers of women, because Allah has given the one more (strength) than the other, and because they support them from their means. Therefore the righteous women are devoutly obedient, and guard in (the husband´s) absence what Allah would have them guard. As to those women on whose part ye fear disloyalty and ill-conduct, admonish them (first), (Next), refuse to share their beds, (And last) beat them (lightly); but if they return to obedience, seek not against them Means (of annoyance): For Allah is Most High, great (above you all).”
Interpretation of this verse:
[Tafsir Ibn kathir]
(Therefore, the righteous) women,
(are Qanitat), obedient to their husbands, as Ibn `Abbas and others stated.
(and guard in the husband’s absence) As-Suddi and others said that it means she protects her honor and her husband’s property when he is absent, and Allah’s statement,
(what Allah orders them to guard.) means, the protected ?husband? is the one whom Allah protects. Ibn Jarir recorded that Abu Hurayrah said that the Messenger of Allah said,
(The best women is she who when you look at her, she pleases you, when you command her she obeys you, and when you are absent, she protects her honor and your property.) Then, the Messenger of Allah recited the Ayah,
(Men are the protectors and maintainers of women, ) until its end….
Brothers, you should know the value of such noble woman [in your life] if you happen to marry one with and gives its due respect.
