PAS funds come from having over one million members, said party president Abdul Hadi Awang today.
"So don't be confused about where PAS gets its money from," Hadi said at a press conference in Marang, Terengganu.
He added the large membership base were even able to set up thousands of pre-schools and hundreds of schools.
A video of the press conference was uploaded onto Facebook.
Hadi was commenting on the MACC's probe into allegations the party received RM90 million from former prime minister Najib Abdul Razak.
PAS has denied the allegation.
Nevertheless, Hadi said the party will give its full cooperation to the MACC.
However, he said other parties should also be investigated.
"Investigate DAP and Amanah [...] probe from where these parties got money to spend during the elections," he said.
