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 beatin g 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.' "
