The mosque has an important place in the religious folklore of Istanbul. The vest (mantle) of the Prophet was taken at the beginning of 17th century from Şükrullah Üveysi of the family el-Karani by the firman of Sultan Ahmed I. After being preserved in several places, it was finally placed in the mosque, which was built for this very purpose.

From the fifteenth day of the month of Ramazan to religious night of Kadir, Hırka-i Şerif is open for visitors in the break between the noon and midafternoon prayers. During the construction of the mosque many buildings nearby were built as adjuncts to the mosque, such as a mortmain for the eldest member of the Üveysi family, an office for the deputy, barracks for soldiers (this building which is presently used as Hırka-i Şerif Primary School), and rooms for those on duty.

One can enter the yard through three gates. They are made of hewn kefeki stone. The mosque has two minarets, each with a single balcony. A dome with eight windows covers the eight-edged mosque. Above the gate on the right hand side of the yard there is a calligraphic epitaph by Kazasker Mustafa İzzeddin, under Sultan Abdülmecid’s monogram. Below the dome, eight framed verse inscriptions made by the same calligrapher can also be seen. Eight framed inscriptions are displayed above the mimbar, which are Abdülmecid’s own work and bear his signature. The preacher desk, mihrab and mimbar are made of red porphyry.
