Four churches were hit by petrol bombs on Friday and Saturday, with the Metro Tabernacle church in the capital worst hit, the first level of its three-storey building gutted by fire.
No one has been hurt in the attacks so far and all the churches aside from Metro Tabernacle have suffered minor damage.
Police also received reports of cars displaying Christian symbols having their windscreens smashed in the capital on Saturday.
And police received a complaint on Saturday that a stone had been thrown at a glass door of a Muslim prayer room known as a surau, in the port town of Klang, said Khalid Abu Bakar, the police chief of Selangor state where three of the churches were attacked.
But he said rumours of attacks on a mosque were unfounded.
A Malaysian court had on December 31 overturned a government ban on non-Muslims using the word "Allah" in their literature, allowing Roman Catholic newsletter, the Herald, to use the term to refer to God in the Malay language.

The judge has since suspended the implementation of the ruling, after the government appealed and the Roman Catholic church agreed to the suspension.
Muslim groups held protests after prayers on Friday against the court overturning the "Allah" ban.
Muslims in Malaysia argue that the "Allah" is exclusive to Islam, and its use by Christians would confuse Muslims.
But Catholic church officials say that for Christian indigenous tribes in East Malaysia, who are the main readers of the Herald's Malay-language edition, "Allah" is the only word they have known for God for decades.
Despite the attacks and tensions, thousands of Malaysian Christians, which make up about nine per cent of Malaysia's 26 million population, turned up for worship services on Sunday.
