The duration of the prohibited time when the sun rises

The questioner:
He says: Honorable Shaykh, may Allah grant you success, one of the prohibited times is from when the sun rises until it passes its zenith. What is the duration of that in minutes now? Is it ten minutes before the adhan for the midday prayer?

The Shaykh:
One does not look at the minutes; one looks at the sun, or rather, one looks at the shadow. When the shadow shrinks from the east and the west and no shadow of the sun remains in the middle, prayer is not permissible. When the shadow begins from the side of the people, they see a point, because the sun has passed its zenith, , meaning the passing of the sun. When a shadow appears from the east, prayer becomes permissible, whether obligatory or voluntary. Yes.

The questioner:
He says: Honorable Shaykh, may Allah grant you success, is the sunnah of the midday prayer four rak'ahs?

The Shaykh:
And as for after the sun rises, this is known by looking at the sun. When it rises above the horizon, when it rises and moves away from the horizon, prayer becomes permissible.
