The Sidi Saiyyed Mosque, known locally as Sidi Saiyyed ki/ni Jali, was built in , is a mosque in Ahmedabad. As attested by the marble tablet fixed on the wall of the mosque, it was built by Shaikh Sa'id Al-Habshi Sultani. Sidi Sa'id was originally a slave of Rumi Khan, a Turkish general who had come to Gujarat from Yemen, bringing along with him his Habshi slaves. Sidi Sa'id later served
Sultan Mahmud III, and upon his death, joined the
Abyssinian general Jhujhar Khan. Upon Sidi Sa'id's retirement from military service, Jhujhar Khan granted him a
jagir. Sidi Sa'id over his career became a prominent nobleman: he collected a library, owned over a hundred slaves, performed the
Hajj pilgrimage, and instituted a langar (public kitchen). Previously at the site there was a smaller brick mosque, which was rebuilt by Sidi Sa'id, and he was buried near the mosque when he died in 1576. The mosque was built in the last year of the existence of
Gujarat Sultanate. During the British colonial period, it served as an office or
kachery for the Mamlatdar of Dascrohi taluka. During its time as an office, doors were installed, the
mihrabs were converted into presses, and the interior was whitewashed. During an official visit to Ahmadabad,
Lord Curzon, Viceroy of India, ordered the Mamlatdar's office to vacate the premises, as part of his wider policies of preserving historic monuments. == Architecture ==
