Also on Monday, Judge Mohamed Nagui Shehata announced he had reserved June 23 as the date to pronounce the verdict against three other Al Jazeera journalists, who are accused of reporting "false news" and aiding the banned Muslim Brotherhood.
Baher Mohamed, Peter Greste and Mohamed Fahmy have now been held for 170 days on charges that Al Jazeera strongly denies.
Commenting on the Egyptian prosecutor's statement that Elshamy would be released, a spokesman for Al Jazeera said:
"This is a relief rather than a cause for celebration. Abdullah has been through a terrible ordeal for over ten months. He'll want to spend time with his family and recuperate. When he's ready, we look forward to seeing him back in action, doing the vital job of journalism that he so clearly loves."
Al Jazeera English journalists Peter Greste, Baher Mohammed and Mohammed Fahmy are still behind bars, and Al Jazeera continues to call for their freedom. A verdict in their case is due on 23rd June.
Egyptian prosecutors have demanded the maximum penalty of 15-25 years in jail for all defendants, but defense lawyers and relatives expect the accused to be acquitted.
The prosecution has submitted as evidence items including a pop video by Gotye, a faked photograph, a BBC podcast and videos made outside of Egypt about an animal hospital.
The three are among 20 defendants in the trial, including 16 Egyptians charged with joining the Brotherhood, which was designated a "terrorist" organization in December.
"Today was the final summation by the defence, again the weaknesses of the prosecution case has been exposed. On the balance of arguments, Al Jazeera hopes the judge will take into consideration the facts presented to him and acquit Peter, Baher and Mohammed of any wrong doing," said Al Jazeera's spokesman Osama Saeed.
"On June 23, the entire world will be watching Egypt to see whether they uphold the values of press freedom.”
Nine of the 20 defendants are in custody, with the rest being tried in absentia.
During the hearings Greste, a Peabody Award-winning journalist, and his co-defendants have denounced the trial as "unfair and political," charging that the evidence against them had been "fabricated."
Some of their co-defendants have claimed to have been tortured in prison. "For six months now we have been treated like terrorists with weapons," Fahmy told the court on Monday.
"A television channel cannot destroy a country," said Fahmy. The authorities have previously said that the accused were operating in Egypt without any valid media accreditation.
