No wife beating in the Quran. Please read the following translations of verse 4:34
[QXP] Men are the protectors and maintainers of women. They shall take full care of women with what they spend of their wealth. Allah has made men to excel in some areas and women to excel in some areas. Men must see to it that women are provided for, and that they are able to stand on their feet in the society. So, righteous women are obedient to Allah's Ordinances and guard their moral values even in privacy, the Values that Allah Commands to be guarded. If you experience rebellion from women, and they stand up against you, apprise them of possible consequences. Next, leave them in their resting places apart from you. And keep admonishing them with examples that they stop rebelling. If they pay heed to you, seek not a way against them. Allah is Most High, Great.
[George Sale] Men shall have the pre-eminence above women, because of those advantages wherein God hath caused the one of them to excel the other, and for that which they expend of their substance in maintaining their wives. The honest women are obedient, careful in the absence of their husbands, for that God preserveth them, by committing them to the care and protection of the men. But those, whose perverseness ye shall be apprehensive of, rebuke; and remove them into separate apartments, and chastise them. But if they shall be obedient unto you, seek not an occasion of quarrel against them; for God is high and great.
[Maulana Ali] Men are the maintainers of women, with what Allah has made some of them to excel others and with what they spend out of their wealth. So the good women are obedient, guarding the unseen as Allah has guarded. And (as to) those on whose part you fear desertion, admonish them, and leave them alone in the beds and chastise them. So if they obey you, seek not a way against them. Surely Allah is ever Exalted, Great.
[Free Minds] The men are to support the women by what God has gifted them over one another and for what they spend of their money. The upright women who are attentive, and keep private the personal matters for what God keeps watch over. As for those women from whom you fear a desertion, then you shall advise them, and abandon them in the bedchamber, and separate from them; if they obey you, then do not seek a way over them; God is High, Great.
