Does the prayer become invalid if one does not prostrate with the nose?

The questioner:
May Allah reward you, Honorable Shaykh. This questioner says: If a person does not touch the ground with his nose in prostration, whether out of ignorance or forgetfulness, does that diminish his prayer or invalidate it?

The Shaykh:
The Prophet (peace and blessings be upon him) pointed to his forehead and his nose, so it is necessary to prostrate with the nose along with the forehead. The one who does not prostrate with his nose is deficient; his prostration is deficient. However, we do not say it is invalid; we say it is deficient and contrary to the guidance of the Prophet (peace and blessings be upon him).

The presenter:
May Allah reward you, Honorable Shaykh. And this questioner says: Some people, when rising from bowing...

The Shaykh:
If he prostrates with his nose only and does not prostrate with his forehead, there is no doubt that this is invalid, because the primary requirement is the forehead. So if he prostrates with his nose and not with his forehead without a valid excuse, his prostration is invalid. As for the reverse, prostrating with his forehead is the primary requirement, but raising his nose is contrary to what is best, contrary to what is most complete. Yes.
