Was standing in night prayer obligatory upon the Prophet (peace and blessings be upon him)?

The questioner:
We ask Allah for your sake regarding standing in night prayer: Is it obligatory for the Messenger (peace and blessings be upon him)?

The Shaykh:
The correct view is that it is a voluntary prayer (nafilah). Arguing with a voluntary prayer is a matter of recommendation, because the Messenger said that prayer is in five [prayers], and the Friday prayer is on a Friday. He mentioned that when she asked if he had made it obligatory for others, he said, "No, except as a voluntary act," and this was included in his address (peace and blessings be upon him).

The questioner:
So it is recommended for us.

The Shaykh:
And so on, and the reward for all of it is confirmed for everyone.

The questioner:
It is not confirmed.

The Shaykh:
For everyone. Every

The questioner:
Every month, some days.

The Shaykh:
All of it.
