What is the evidence for distinguishing between the ghusl for menstruation and the ghusl for major ritual impurity?

The questioner : Well, Shaykh, excuse me, regarding menstruation, you distinguished here between menstruation for a woman and, well, major ritual impurity.

The Shaykh: Yes.

The questioner : Shaykh, is there evidence for this statement?

The Shaykh : Well, there is a hadith in Sahih Muslim.

The questioner: Yes.

The Shaykh : That the Messenger (peace and blessings be upon him) ordered the woman.

The questioner: Yes.

The Shaykh : If she is in a state of major ritual impurity.

The questioner: Yes.

The Shaykh : To pour water over her head.

The questioner: Yes.

The Shaykh : And as for if she is menstruating, to unbind the hair of her head.

The questioner : Yes, meaning he distinguished between this and that.

The Shaykh: Yes.
