"We lost the two Tests because of our poor batting and that is all," Sarfraz said.
"If they could win Test matches because of witchcraft or magic, then they should have also won the ODI and T20 series," the Pakistan skipper told the media here.
Chandimal told reporters after returning to Colombo that he had received a special blessing from a meyni, or sorcerer, ahead of the two-Test series against Pakistan in the United Arab Emirates.
"I believe in the holy Quran and also that there was magic in the world, but in the Test series we just batted badly and lost chances to win," said Sarfraz.

He made it clear that while luck played a part in cricket but matches were won and lost on the field by players by their performances.
Pakistan's former Test skipper Muhammad Yousuf also rubbished Chandimal's claims.
"Don't mix cricket with such things. Pakistan's planning was bad and they messed it up," said Yousuf.
Chandimal's comments came after Sri Lanka's Sports Minister had earlier denied that he had sent the captain to a sorcerer to get blessings for the Test series.
