"We accepted the extension offers immediately because we feel comfortable here at Lierse," Egypt international Abdul-Wahed told FilGoal.com.
The duo had initial contracts until the end of the current season, which will be the first for Lierse in the top flight since 2006-2007.
Meanwhile, another Egyptian who was not offered a new contract is wing-back Ahmed Samir, who was linked with a move to Zamalek last season.
Samir's contract with the Egyptian-owned club runs out by the end of the term.
Lierse kickoff their season against Sint-Truidense on Saturday.
