Taj Al-Din Ebrahim ibn Rushan Amir Al-Kurdi Al-Sanjani (or Sinjani) (1216–1301), titled Sheikh Zahed (or Zahid) Gilani, was Grandmaster (Murshid Kamil) of the famed Zahediyeh Sufi Order at Lahijan. He is well-known as Sultân-ûl Khalwatiyya Tadj’ad-Dīn Ebraheem Zāheed al-Geylānī, as well.
Since the mid 13th century, Sheikh Zahed is revered as a spiritual authority and his tomb near Lahijan in Iran's Gilan Province, on the shores of the Caspian Sea, draws numerous pilgrims to the picturesque village of Sheikhanvar. His ancestors hailed from the ancient Iranian city of Sanjan in Khorasan (located in present day Turkmenistan).
This historical structure is situated in the Sheikhanvar village of Lahijan. The same is relevant to Tajeddin Ebrahim or Sheikh Zahed Gilani. The structure covered with earthenware tiles is of a pyramid shape, with a pointed dome and ceiling of plaster work. The only inscription on the wooden chest on the tomb reveals the date of 832 AH. The architectural style of the structure displays the effects of the 8th or 9th century AH. The same has been on record in Iran.
