Iyas ibn Abdullah ibn Abu Dhubab reported the Messenger of Allah (ﷺ) as saying: Do not beat Allah's handmaidens, but when Umar came to the Messenger of Allah (ﷺ) and said: Women have become emboldened towards their husbands, he (the Prophet) gave permission to beat them. Then many women came round the family of the Messenger of Allah (ﷺ) complaining against their husbands. So the Messenger of Allah (ﷺ) said: Many women have gone round Muhammad's family complaining against their husbands. They (those husbands who take to beating their wives) are not the best among you.
