Qatada قتادة · The Book on Hajj

"We were with the Prophet on a journey (on the Day of) Adha, so seven of us shared in a cow, and ten for a camel."

"I said: 'O Messenger of Allah! What should be done with the afflicted among the Hadi?' He said: 'Slaughter them, then dip their sandals in their blood, then leave them so that the people can eat them.'"

The Messenger of Allah said: "May Allah have mercy upon those who shaved" saying it one or two times, then he said: "And those who shortened."

"The Messenger of Allah prohibited that a woman should shave her head."
