Question

what is a mihrab? what is its function?

Answer 1

Mihrab (Arabic: محراب‎ miḥrāb, pl. محاريب maḥārīb) is a semicircular niche in the wall of a mosque that indicates the qibla; that is, the direction of the Kaaba in Mecca and hence the direction that Muslims should face when praying. The wall in which a mihrab appears is thus the "qibla wall".

Mihrab (niche) Another essential element of a mosque's architecture is a mihrab—a niche in the wall that indicates the direction of Mecca, towards which all Muslims pray. ... No matter where a mosque is, its mihrab indicates the direction of Mecca (or as near that direction as science and geography were able to place it).
