To  Sun Devil.  Thank You for Answering me.
You are Correct -  Adultery is illegal in Islam and - punishable with death.   But the MEN in  ISLAMIC Doctrine and Islamic Teaching  -  are Allowed to Hire Women for any amount of time.   an Hour or two, A Day or Two or a Month,  Just to have a Sexual eXchange for a SUM of Money or a Gift. .  
This is Adultery in the Bible and If they are Caught in the USA doing that.  They Could Be Committing A CRIME.
Because if the Muslim MAN is LEGALLY Married to a Woman and then Hires a Muslim Woman for this sexual Encounter,   He CAN NOT Legally Marry Her.  So he Is committing  adultery  .  by  the  LAWs  -  OF THE UNITED STATES.  -  And Many Other Countries.  
Polygamy is not LEGAL in the USA,...  An American Man Can Have sex with 40 women a week and have Homosexual seX with 40 Men As well all in the Same WEEK.   BUT  if He  Marries  More than One Partner,  He is Breaking the LAW.  and  To HIRE  another Woman, jUST For seX for a Period of Time. IS Called ADULTERY. and Prostitution.   
You can CALL it What You Would Like.   LOOKING through the Eyes of  ISLAMIC Law.   But  YES  Adultery and Prostitution is Condoned, Practiced and Sanctioned in  ISLAM.
. But    *(  BY The Biblical and American LAWs and Standards...  it is NOT,  -  OK.     Please Re Read the Facts and Support the Truth,
Men are not Killed or Punished in ISLAM. for Having a Few Hours of a sexual FLING with another Islamic Woman, Who has been Paid Money or Gifts,./     They Call this Marriage.  Even if the Woman Has been with 100 Other Men .   She Can DIVORSE and Re- Mary Forever.
If the HUSBAND decides to Keep her for a few more Hours, Days or Months.   She Can be PINISHED or Killed for Going to another Customer. and Committing Islamic Adultery  !
