What is the ruling on shaving the head at Muzdalifah?

The questioner : And that a person, based on this hadith, at Muzdalifah said, "Now the acts of the day of 'Id have begun in the morning," and he shaved at Muzdalifah.

The Shaykh : Yes, the Messenger (peace and blessings be upon him) was asked about this in Mina, and no one can do it before leaving Muzdalifah.

The questioner : On this basis, it must be specified that he must leave first and then begin.

The Shaykh : It is well known, yes, because this question was asked on the day of 'Id.
