The mausoleum of Imamzadeh Seyyed Soleyman in Fakhrabad is a square-shaped structure with a domed roof made of bricks. Its exterior features a vaulted design, while the interior walls are adorned with the name of Allah and wall paintings embellished with geometric and Islamic motifs.
According to research conducted by an institute in Khorasan, he is the direct descendant of Imam Musa al-Kadhim (peace be upon him), residing in Balkh. He migrated to Shiraz for political and social reasons, after the dominance of Umayyad dynasty, and later, at the request of the people of Fakhrabad, settled there permanently. He passed away in the late first half of the fifth century.
