Jabir ibn Abdullah al-Ansari is known as one of the long-lived companions and a prolific transmitter of hadith. According to TDV sources he died and was buried in Medina. The station attributed to him inside the Atik Mustafa Pasha (Hazreti Câbir) Mosque in Ayvansaray, Istanbul, is a symbolic site belonging to the Ottoman culture of visitation; sources are divided over whose station it is (Jabir ibn Abdullah or Jabir ibn Samura). The tradition that he took part in the sieges of Constantinople rests largely on Ottoman popular lore. It is therefore recorded here as a maqam of contested grave-identity, with the actual burial in Medina. The separate station at Düğmeciler in Eyüp belongs to his son Jabir ibn Muhammad al-Ansari and should not be confused with it.
