I know, sadly, that most if not all will read the very extensive link I provided about how to interpret 4:34, so here's the essence. That 4:34 only applies to "manifest indecency" first. That the remedies are first to kindly let her know that this is a probem, then to refuse to sleep with her and then only to "tap" in a symbolic way. The emphasis below is mine:
Moreover we should remember that a husband is "only" allowed to resort to this option [ which certainly cannot be called or labeled as physical abuse or wife beating ] in case his wife is guilty of some manifest indecency [ nushuz ]. In dealing with a wife in "nushuz" , a husband should first first try his best to rectify her attitude by kind words, gentle persuasion, and reasoning with her [ reminding her of God and His teachings ]. If this is not helpful, he should sleep apart from her, trying to awaken her agreeable feminine nature so that serenity may be restored and she may respond to him in a harmonious fashion. If this approach fails, it is permissible for him to hit/tap her lightly, avoiding her face and other sensitive areas. This rule is based on Prophet's statement in the Farewell Pilgrimage hadith, which describes the "only" permissible form of discipline in this case as "ghayr mubarrih" which means: "non" violent , brutal or painfull [ see: authentic traditions in Muslim, Tirmidhi, Abu Da'ud, Nasa'i and Ibn Majah ]. Therefor it's clear that this light hit/tap, if resorted to at all, is more symbolic by which the husband as a last resort expresses his anger and frustration in the hope to bring back his wife to consiousness; i.e. to make her realize that her marriage is on the edge of divorce [ in order to make her stop her lewd behaviour and/or immoral conduct ]. And finally again we should remember that any form of abuse [ physical and verbal ] is strict forbidden in islam. This is clearly stated by our beloved Prophet Muhammad in the next famous authentic hadith:
The Prophet said: "There shall be no infliction of harm on oneself or others". [26]
