Did the Prophet (peace and blessings be upon him) leave off the closing salam in a voluntary prayer or an obligatory one?

The questioner:
Another path. They. The Prophet (peace and blessings be upon him) left off the closing salam; was it a voluntary prayer or an obligatory one?
The Shaykh:
It was a voluntary prayer. The engagement means he leaves off the work, seeking refuge in Allah from the evil of the voluntary prayer, perhaps Allah will protect him from its harm.
The questioner:
It is permissible to raise the head to the sky in a voluntary prayer.
The Shaykh:
In a voluntary prayer, he does not raise it. The one who prays does not raise his head; he looks at the place of his prostration. The Messenger said: "Let them stop, or their eyes will be plucked out." This applies to neither the obligatory nor the voluntary prayer; he does not raise it.
