The ruling on drawing a part of the body other than the head

The questioner:
Well, Shaykh, what about drawing or depicting a part of the body, like the foot or the hand only, Shaykh?

The Shaykh:
If it is within the scope of necessity, there is no harm. The head, no.

The questioner:
Yes, and other than the head.

The Shaykh:
There is nothing wrong with it, if Allah wills.

The questioner:
Well, the hadith, Shaykh, about the head image, if it is...

The Shaykh:
What? The head image.

The questioner:
The image of the head, so if the head is cut off, there is no image. Is this hadith established?

The Shaykh:
The hadith is good, good.

The questioner:
Good, Shaykh, if one draws the foot or any part of the body other than the head.

The Shaykh:
If it is not for a need, there is no harm.

The questioner:
I do not mean, for example, that I am a teacher and I am explaining to the students, and I drew a foot or a hand.

The Shaykh:
For a need, there is no harm.
