Lukaku has been suffering from a hamstring injury which, coupled with a thigh problem earlier this season, means he has played just twice since August and is currently sidelined for his club Inter Milan.
But Martinez has previously stated that as long as Lukaku could play in one of Belgium's Group F games against Canada, Morocco, or Croatia, he would take him to the tournament.
Hazard has been mostly on the sidelines at Real Madrid this season and has not played in LaLiga since September having fallen out of favour with coach Carlo Ancelotti.
However, he is a talismanic figure for Belgium and Martinez has set aside concerns with his match fitness and form.
Belgium, who finished third at the World Cup four years ago, start their 2022 campaign against Canada on November 23rd.
Belgium squad:
Goalkeepers: Thibaut Courtois, Simon Mignolet, Koen Casteels
Defenders: Jan Vertonghen, Toby Alderweireld, Leander Dendoncker, Zeno Debast, Arthur Theate, Wout Faes
