Some Houston residents are upset after Korans were left on the doorsteps of hundreds of homes in their neighborhood as part of a campaign to educate people about Islam.

Residents of Braes Timbers in southwest Houston began finding the holy books two weeks ago, MyFOXHouston.com reported. The Korans came with a note saying they had been left by the Book of Signs Foundation, which claims to have distributed 30,000 free copies of the texts to residents throughout the city.

"If we went into a Muslim country and left a Bible, we would be in prison and then decapitated a few years later," Sue Ann Pieri, a resident who chose not to destroy the book, as other neighbors did, told MyFOXHouston.com.

The foundation, which left the books on doormats or hanging from doorknobs, said in a note accompanying the Koran that "rather than judging Islam and Muslims by the actions of a few, we want our fellow citizens to judge us by the book that influences and guides the lives of over 1 billion Muslims."

Tarick Hussein, the president of Houston's Council on American-Islamic Relations, told the station he believes the Book of Signs Foundation wants to educate non-Muslims about the religion.

He told MyFOXHouston.com: "This is a very peaceful way of conveying a message."
