Allah said,

﴿فَإِنْ أَطَعْنَكُمْ فَلاَ تَبْغُواْ عَلَيْهِنَّ سَبِيلاً﴾

(but if they return to obedience, seek not against them means (of annoyance),) meaning, when the wife obeys her husband in all that Allah has allowed, then no means of annoyance from the husband are allowed against his wife. Therefore, in this case, the husband does not have the right to beat her or shun her bed. Allah's statement,

﴿إِنَّ اللَّهَ كَانَ عَلِيّاً كَبِيراً﴾

(Surely, Allah is Ever Most High, Most Great.) reminds men that if they transgress against their wives without justification, then Allah, the Ever Most High, Most Great, is their Protector, and He will exert revenge on those who transgress against their wives and deal with them unjustly.

﴿وَإِنْ خِفْتُمْ شِقَاقَ بَيْنِهِمَا فَابْعَثُواْ حَكَماً مِّنْ أَهْلِهِ وَحَكَماً مِّنْ أَهْلِهَآ إِن يُرِيدَآ إِصْلَـحاً يُوَفِّقِ اللَّهُ بَيْنَهُمَآ إِنَّ اللَّهَ كَانَ عَلِيماً خَبِيراً ﴾

(35. If you fear a breach between the two, appoint (two) arbitrators, one from his family and the other from her's; if they both wish for peace, Allah will cause their reconciliation. Indeed Allah is Ever All-Knower, Well-Acquainted with all things.)
