PAS spiritual leader Hashim Jasin said parties wanting to cooperate with PAS should be willing to unequivocally accept Islam's position and amendments to Act 355, Bernama reported.
He said PAS did not look at race or religion, as the important goal was to forge unity among people for the country's well-being.
"Although PAS is an opposition party...it definitely wants to give advice, we should be united on the same matters and not split over differences," he reportedly said in Jejawi, Arau yesterday.
If passed by Parliament, amendments to Act 355, pushed by PAS through a private member's bill by its president Abdul Hadi Awang, will pave the way for the hudud.
Opposing views on the hudud held by DAP and PAS led to the break up of Pakatan Rakyat in 2015, and the formation of Pakatan Harapan consisting of DAP, PKR and PAS splinter party Amanah.
Hadi last week said PAS is open to discuss forming an electoral pact to ensure straight fights with BN in the next general election, with condition that the other parties do not meddle in PAS' internal affairs.
Speaking to reporters yesterday, Hadi said the party will not negotiate with parties that "steal the things from our house".
"It depends on the parties which want to cooperate with PAS, that they must clearly understand that PAS is the main engine driver. We have no problem in moving alone, and not just in wanting to win the elections," Hadi reportedly said.
This comes as Harapan extends an invitation to PAS and other opposition parties to its convention this Saturday, in what looks like a bid to hammer out an electoral pact for the 14th general election.
Parti Pribumi Bersatu Malaysia (Bersatu) also said it has set a meeting with PAS to discuss the matter.
