Does staying in the part of Masjid Namira that is within the boundaries of Arafat after zawal until sunset count as standing in Arafat, or is it obligatory to go out to Jabal Ar-Rahmah?

Staying in the part of Namirah Mosque that is within the boundaries of Arafat from after the sun's zenith until sunset is considered a valid standing (wuquf), and there is no condition to exit the mosque. Al-Nawawi indicated that the front part of the mosque, from the direction of Wadi Arafat, is not within Arafat, whereas its rear part is within Arafat. Therefore, whoever stands in its rear part has performed a valid standing.
