Ibrahim Zahid al-Gilani (c. 615/1218 – 700/1301) was born in the Siyavrud district of Gilan; he became a disciple of Sayyid Jamal al-Din al-Tabrizi and the pir of the Zahidiyya order. His successors include Safi al-Din al-Ardabili (his son-in-law, founder of the Safaviyya) and Akhi Muhammad al-Khalwati, the opening link of the Khalwatiyya. According to the TDV encyclopedia he died in Siyavrud; his grave is disputed — both the mausoleum in Shikhakaran village of Lankaran, Azerbaijan (said to have been relocated in the 17th century after Caspian flooding; rebuilt in 2006) and the Sheikh Zahed shrine at Lahijan, Iran, are attributed to him, so no coordinates are given.
