DAP's behaviour will cause calamity for Pakatan Harapan by creating opportunities for BN to attack the opposition coalition, said PAS vice-president Idris Ahmad.
This was mostly due to Sarawak DAP's recent call for the state government to stop recruiting Islamic religious teachers from Peninsula Malaysia.
The call was made by Kuching MP Chong Chieng Jen in Parliament last week.
"DAP's antics heralds a dark future for the opposition. Chong, who talked about restricting religious teachers from the Peninsula, will give more Umno and BN more confidence," said Idris.
