Muhammad bin al-Muthna - al-Zaman محمد بن المثنى أبو موسى - الزمن · Chapters on Sacrifices

“The son of Adam does not do any deed on the Day of Sacrifice that is dearer to Allah than shedding blood. It will come on the Day of Resurrection with its horns and cloven hoofs and hair. Its blood is accepted by Allah before it reaches the ground. So be content when you do it.”

“The Messenger of Allah (ﷺ) slaughtered a cow on behalf of all his wives who had performed ‘Umrah, during the Farewell Pilgrimage.”
