hmmm...not sure what exact word was used but those folk at Jericho got exterminated somehow....every man, woman and child.
FWIW
Muslims must wash (or pretend to wash, if water is lacking, which is not unusual) face,hands, nose, mouth, ears, feet and nether regions 5 times a day, before salat (Prayer, o Infidel dog).
This is why it is written, only a brave frogman in a rubber suit should share sanitary facilities with our Muslim brothers. (Don't believe me? Fly SaudiAir.)
However, any religion which encourages Third Worlders to wash (or pretend to wash) their nether regions 5 times a day may have some redeeming value somewhere. However, I must point out that if Muslims insist on killing people who do not immediately adopt their habits, appreciating any value their customs might have becomes somewhat problematical.
