Respect women's rights regardless of their social status or economic situation.

This hadith teaches us about the rules regarding the divorce of a slave woman. According to this hadith, the divorce of a slave woman is twice and her waiting period is two menstrual cycles. This means that if she gets divorced, she must wait for two menstrual cycles before getting married again. This rule was set by Prophet Muhammad (peace be upon him). It shows us how important it was for him to protect women's rights even in those times when slavery was still practiced. He wanted to make sure that women were treated fairly and with respect regardless of their social status or economic situation.
