Maqsurah

Maqsurah (Arabic: مقصورة, literally "closed-off space") is an enclosure, box, or wooden screen near the mihrab or the center of the qibla wall in a mosque.

Uthman's initial maqsura was a simple mudbrick wall pierced with holes so that he could not be approached but could still be seen by worshippers during prayers.

It is located directly to the right of the mosque's minbar, and is notable for its woodwork which includes an elaborately carved Kufic inscription dedicated to al-Mu'izz.

[4]Maqsuras continued to be built for some mosques throughout the Islamic world afterwards, though the term also came to denote other kinds of rooms or spaces which do not appear to have been necessarily reserved for the ruler.

One was probably present in the original Fatih Mosque built by Mehmed II the Conqueror (which was destroyed by a later earthquake and rebuilt).
