The Prophet (peace and blessings be upon him) ordered me to carry out the prescribed punishment on her. I saw that her bleeding would not stop, so I came and mentioned this to the Prophet (peace and blessings be upon him).

Carry out the prescribed punishments on your male and female slaves as well."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) initially forbade visiting graveyards, using specific utensils, and keeping the meat of sacrificial animals for more than three days.

I also forbade you from using specific utensils, now you may use them for drinking, but avoid intoxicating things. And I forbade you from keeping the meat of sacrificial animals for more than three days, now you are permitted to keep it for as long as you wish."

I felt shy to ask the Prophet (peace and blessings be upon him) about this issue myself because his daughter was married to me. So I asked Sayyiduna Miqdad (may Allah be pleased with him), and he asked the Prophet (peace and blessings be upon him) about this issue.

Therefore, when you see madhiy, wash your private part and perform ablution as you do for prayer."
