Zamalek made an official enquiry about the gifted 25-year-old player but the Dervishes’ officials said that he is not for sale.
The White Knights' offer also included the transfer of left wing-back Sabry Rahil, plus cash on the table.
El-Said, who scored eight goals last season, has two years remaining on his contract with the club, but was rumoured to be on his way out because the club’s financial troubles mean that they can’t meet his demands.
El-Said is one of the hottest talents in the Egyptian Premier League and produced an impressive performance with Ismaily last season, helping the team to reach the Confederation of African Football (CAF) Cup, after ending third in the league table.
On the other hand, Ismaily president Nassr Abou El-Hassan is believed to be open to discussing Zamalek’s offer concerning defender El-Moatassem Salem.
Salem’s contract expires in summer 2012 and he could leave the club next January in a free transfer.
