A group of American Islamic scholars recently ruled that Muslims should not pass through full-body scanners being used to detect weapons in airports.

The Fiqh Council of North America said the technology, which allows Transportation Security Administration screeners to see items hidden under clothing, violates Islamic laws against nudity.

"It is a violation of clear Islamic teachings that men or women be seen naked by other men and women," reads the order, called a fatwa. "Islam highly emphasizes haya (modesty) and considers it part of faith. The (Koran) has commanded the believers, both men and women, to cover their private parts."

However, TSA has said those who are uncomfortable with the scanners can submit to a pat down instead.

"TSA is committed to treating all passengers with respect and dignity during the screening process," TSA spokeswoman Sarah Horowitz said.

About 450 full body scanners are expected to be installed in airports across the U.S. this year.
