"It was narrated that Iyas bin 'Abdullah bin Abu Dhubab said: "The Prophet said: 'Do not beat the female slaves of Allah.' Then 'Umar came to the Prophet and said: 'O Messenger of Allah, the woman have become bold towards their husbands? So order the beating of them,' and they were beaten. Then many women went around to the family of Muhammad,. The next day he said: 'Last night seventy women came to the family of Muhammad, each woman complaining about her husband. You will not find that those are the best of you.' " (Sahih)"
