The mosque was established by Sidi Sayed, a slave of Sultan Ahmed Shah. Sidi Sayed mosque in Ahmedabad, India consists of ten semi circular windows, the appeal of which is accentuated by the splendid mesh covering them, which is more popularly known as 'Jali'. The Jali screen windows represent the Indo-Saracenic styling, which is admired by people all over the world.
Consisting of delicately carved windows, the mosque is known for its stone tracery. The construction work of the Sidi Sayed mosque was taken up in the last year of the Sultanate rule in Gujarat.The mosque was built in the last year of the existence of the Sultanate of Gujarat The rear wall is filled with square stone pierced panels in geometrical designs. The two bays flanking the central aisle have reticulated stone slabs carved in designs of intertwined trees and foliage and a palm motif. This intricately carved lattice stone window is the Sidi Saiyyed Jali, the unofficial symbol of the city of Ahmedabad and the inspiration for the design of the logo of the Indian Institute of Management Ahmedabad. The central window arch of the mosque, where one would expect to see another intricate Jali, is instead walled with stone. This is possibly because the mosque was not completed according to plan before the Mughals invaded Gujarat.
