Opposition parties which wish to cooperate with PAS must leave DAP before negotiations can be held, said the Islamist party's information chief Nasruddin Hassan.
"The reality is that DAP is still opposed to PAS' Islamic struggle.
"So PAS' current policy is to reject DAP and all parties which work together with DAP," he added in a statement, according to a report in the Harakah Daily.
Therefore, he said the simple equation for those parties which want to be with PAS is to leave DAP and adhere to a simple condition - respect the party’s theocratic struggle.
"This is our solution," he added.
Yesterday, former opposition leader Anwar Ibrahim said Pakatan Harapan and Parti Pribumi Bersatu Malaysia (Bersatu) would hold negotiations with PAS.
He told reporters this following a meeting with Bersatu pro-tem president Muhyiddin Yassin.
Meanwhile, Nasruddin said PAS has vast political experience and is capable of facing the challenges without cooperation with other parties.
"PAS has joined numerous forms of political alliances... Given the experience garnered, it is time for PAS to lead the change. A change towards the well-being of the people and a prosperous nation to please Allah," he added.
The information chief also commented on the allegation that PAS has been influenced by Umno, which he described as slander.
"A thousand and one lies and insults have been hurled at PAS. We have purportedly consumed Umno’s dedak (animal feed), fallen into Umno's trap, duped by Umno and so forth.
"Their objective is to cast a negative perception on PAS.
"But the reality is, PAS is not easily fooled by any quarters. It holds firm to the principles of truth and the Islamic struggle," he said.
