Sayyid Usman Roza is a mosque and tomb complex located in the Usmanpura, a suburb of Ahmedabad on the west bank of the Sabarmati River, just across from the center of the old city. It commemorates Sayyid Usman, a son of Qutb-i Alam Bukhari and brother of Shah-i Alam, both of who have rozas on the southern side of Ahmedabad. Historical sources date the complex, which comprises a mosque and a large tomb to just after his death, circa 1460/864 AH.
The tomb commemorating Sayyid Usman is a large square building sitting on a very slightly raised platform. It consists of a pillared hall open on all four sides (having lost the carved marble screens that once lined the exterior). At the center of the hall, a dome rests on a group of twelve pillars arranged in a circle connected with arches to form an arcade. This arcaded chamber is bounded by twenty pillars arranged in a square, with the corners being groups of four pillars. Surrounding this inner square come two further rows of pillars arranged as concentric squares around it.
Just to the west of the tomb is the complex's mosque. It is one of the earliest of its type: a rectangular building with three solid walls on the south, west (qibla), and north, but open on the east side. Framing the east facade are two ornate tower-minarets. The interior is a pillared hall divided into five aisles parallel to the qibla by five rows of ten free standing pillars. Three mihrabs mark the qibla wall and four windows pierce it. The side walls have two doors each and two windows. The minarets take the form of tapering cylindrical shafts. The surface of these minarets is divided into segments by cornices and further into registers by bands of vegetal ornament. The bottom third of the shafts is fluted.
