Pamela Anderson's plans to donate the earnings from her Playboy cover shoot to an Indonesian disaster relief fund have been slammed by a hardline Islamic group.

Anderson announced the plans on her own website, saying “I’ve just shot another Playboy cover that will debut in January for Hugh Hefner, at his request -- I adore him. Playboy and I decided to do this, so I could donate earnings from the shoot to Waves for Water.”

But the Islamic Defenders Front on Monday told Indonesia's Metro TV that the donation to the charity -- which works to bring clean drinking water to disaster hit zones -- would be "against the law of God" because it was obtained through "immoral acts."

“If she wants to be photographed naked, then she is challenging a bigger disaster to happen in Indonesia. It's haram [forbidden],” Habib Umar Salim, the head of FPI's advisory council said.

Anderson's agent was not available for comment.
