He will be sent back to Bangladesh via a flight from the Kuala Lumpur International Airport on Friday night, the New Straits Times newspaper reported.
A deportation team was scheduled to transport Rayhan to the airport at 9pm local time, Datuk Khairul Dzaimee Daud, director general of the Immigration Department, said in a statement.
K Sumitha Shaanthinni and C Selvaraja, the lawyers for Rayhan, had said in a statement Rayhan would be deported immediately after his COVID-19 screening test results.
Sumitha had said the deportation process would include getting a flight ticket to Bangladesh.
The department arrested him on Jul 24 after Al Jazeera published the documentary "Locked up in Malaysia's Lockdown".
The documentary sparked an immediate backlash online while several officials decried the report as being inaccurate, misleading and unfair.
Al Jazeera said it stood by the "professionalism, quality and impartiality of its journalism" and called on Malaysia to withdraw the criminal investigation.
