The 24-year-old midfielder’s future has come under speculation in recent weeks, with Championship rivals Burnley reported to be interested in him.
BBC Radio Nottingham quoted Forest manager Dougie Freedman as saying at the weekend that he has asked Burnley to include one of their players in the deal.
It seemed that Lansbury’s future lied away from the City Ground, but Al-Hasawi’s tweet this evening suggests that the former Arsenal midfielder will remain at the Championship club.
This will come as good news for Forest, who are aiming for a top-six finish in the Championship this season.
Lansbury has been on the books of the Reds since 2012 and has established himself as one of the most important players in the squad.
The midfielder has started the 2015-16 Championship campaign strongly, creating 14 chances in three league matches.
Lansbury has a pass accuracy of 79%, and has won one header, one dribble and five tackles.
