“It is evident from many authentic Traditions that the Prophet himself intensely detested the idea of beating one’s wife, and said on more than one occasion, “Could any of you beat his wife as he would beat a slave, and then lie with her in the evening?” (Bukhari and Muslim).
According to another Tradition, he forbade the beating of any woman with the words,
“Never beat God’s handmaidens” (Abu Da’ud, Nasa’i, Ibn Majah, Ahmad ibn Hanbal, Ibn Hibban and Hakim, on the authority of Iyas ibn ‘Abd Allah; Ibn Hibban, on the authority of ‘Abd Allah ibn ‘Abbas; and Bayhaqi, on the authority of Umm Kulthum).
When the above Qur’aan-verse authorizing the beating of a refractory wife was revealed, the Prophet is reported to have said:
“I wanted one thing, but God has willed another thing – and what God has willed must be best” (see Manar V, 74).
With all this, he stipulated in his sermon on the occasion of the Farewell Pilgrimage, shortly before his death, that beating should be resorted to only if the wife “has become guilty, in an obvious manner, of immoral conduct”, and that it should be done”in such a way as not to cause pain (ghayr mubarrih)”; authentic Traditions to this effect are found in Muslim, Tirmidhi, Abu Da’ud, Nasa’i and Ibn Majah. On the basis of these Traditions, all the authorities stress that this “beating”, if resorted to at all, should be more or less symbolic – “with a toothbrush, or some such thing” (Tabari, quoting the views of scholars of the earliest times), or even “with a folded handkerchief” (Razi); and some of the greatest Muslim scholars (e.g., Ash-Shafi’i) are of the opinion that it is just barely permissible, and should preferably be avoided: and they justify this opinion by the Prophet’s personal feelings with regard to this problem.(Quran Ref: 4:34 ) ”
The Prophet explained it by “dharban ghayra mubarrih” which means “a light tap that leaves no mark”. He further said that face must be avoided. Some other scholars are of the view that it is no more than a light touch by a siwak, or toothbrush.
To confirm the above concept, the Prophet (peace and blessings be upon him) is reported to have said, “How does anyone of you beat his wife as he beats the stallion camel and then embrace (sleep with) her?” ( Reported by Al-Bukhari)
In another hadith, he is also reported to have said, “Do not beat the female servants of Allaah.”So we conclude Wife-beating is not allowed under no circumstances
