State officials said no one was injured and no damage caused in the early-morning attack after the fire-bomb landed on the centre's metal shutters.
State Deputy Chief Minister P. Ramasamy said the attack may have been prompted by his Facebook post over the weekend about preacher Zakir Naik.
“It could possibly be related to my comment on Zakir as Satan,” he told AFP.
Ramasamy accused Zakir, an Indian national, of giving speeches designed to promote hatred of other faiths.
His posting was not directed against Islam or Muslims but against “this particular person”, he said in a statement.
“I regret the use of the word 'Satan' which has caused uneasiness and unhappiness among Muslims in Malaysia,” Ramasamy said, adding that the word was later deleted
