Sayid Hassan Jarrah (Arabic: سَعِيد حَسَّان جَرَّاح, Sa‘īd Ḥassān Jarrāḥ) is a fictional character from the ABC show Lost portrayed by Naveen Andrews.

Sayid originally served as a communications officer in Iraq's Special Republican Guard and was a skilled radio and mechanical engineer.

He explained that Sayid´s commanding officer had committed war crimes against the civilian population and gave him a tool box saying that Sayid would have to force his CO to give them the information they wanted.

They make him a deal: if Sayid can infiltrate a terrorist cell in Sydney, whose members he is familiar with, and uncover stolen C-4, then they will tell him where Nadia is.

Sayid fixes the transceiver recovered from the cockpit, and leads a group into the jungle in order to send out a distress signal.

Sayid surmises that Rousseau intends to attempt an exchange of Claire's baby for her own child, Alex, with the "Others".

[22] Sayid is soon informed of Naomi's presence, and after speaking to her begins to question her; he is soon taken aback when she gives him her satellite phone, having expected her to have no way to contact her boat.

[23] The next day, Sayid is taken into the jungle, where Jack and Juliet come clean and reveal their secretive plans to destroy the Others.

A person named Sami recognizes Sayid as the man who tortured his wife with boiling oil, and attempts to beat a confession out of him.

[30] Sayid and Desmond later witness Keamy's furious return to the boat after his failed attempt to capture Ben.

[32] However, his and Nadia's happiness is abruptly cut short when she is killed, and Sayid decides to hold her funeral in their home country.

Following this event, Sayid eventually begins working for Ben as an assassin, after being informed that Nadia's death was part of a larger plan orchestrated by Charles Widmore.

The two bond quickly, but the relationship is cut short when Elsa, who works for one of Sayid's targets, learns about his true intentions, and injures him.

[35][36] Upon awakening Sayid refuses to cooperate with Jack and Ben's plan to return everyone to the island; however; he appears the next day in law enforcement custody (whom he could have beaten up and killed) on board the plane.

Sayid's first appearance on the island takes place in 1977, when he vanished along with Jack, Kate, and Hurley en route from Los Angeles to Guam on Ajira Flight 316.

[37] Despite attempts by Sawyer to try to expedite his escape, he refuses to cooperate, leading him to be chemically interrogated by a shaman-like Dharma Initiative member.

[38] Sayid reappears in "Follow the Leader" as Jack, Kate, Richard, Eloise Hawking, a younger Charles Widmore, and an unnamed Other are walking through the jungle towards the hydrogen bomb "Jughead" .

[39] Shortly before "The Incident" is about to occur, Sayid and Jack pose as Dharma employees and attempt to smuggle a core piece of the hydrogen bomb to the Swan Station.

However, the knife proves worthless but the Smoke Monster (in Locke's form) allows Sayid to live and return to the temple with a message.

He then proceeds to confront Dogen and murders him and Lennon, allowing the Smoke Monster into the Temple to kill those who didn't defect.

The "infection" Dogen had spoken of appears to be a type of mind control that the Man in Black has placed over Sayid.

When Widmore's team threatens to waylay their camp with artillery shells, the Man in Black orders everyone to start leaving and asks Sayid to kill Desmond.

Sayid tells Jack where to find Desmond and then sacrifices himself to save the others, taking the bomb and running as it explodes.

Aboard Flight 815, Sayid kicks in a lavatory door to save a passenger, Charlie Pace, who'd locked himself inside.

He runs into a fellow passenger at baggage claim then takes a cab to Nadia and Omer's house, where he meets them and their two children Eva and Sam.

A call takes Omer from dinner early, and the children, looking for presents, find a picture of Nadia in Sayid's bag.

("The Last Recruit") ("What They Died For") ("The End") Sayid was not in the original draft of the pilot episode, but the producers knew early on that they wanted an international cast.

Executive consultant Jeff Pinkner had worked with Naveen Andrews on a short-lived ABC series called The Beast, and was keen to have him on Lost.

[41] A fan favorite since the show's inception, Chris Carabott of IGN stated that in the episode "The Economist" – "Sayid Jarrah is a badass who could give Jack Bauer, James Bond, and Jason Bourne all a run for their money".

She also noted the "subversive" nature of an Iraqi soldier in a series regular role 18 months after the US declared war on Iraq.
