How many of you agree Muhammad the smart AZ arranged to reveal Qur'an 33:51 for blameless sex?

Qur'an (33:51) - "You may put off whom you please of them, and you may take to you whom you please, and whom you desire of those whom you had separated provisionally; no blame attaches to you; this is most proper, so that their eyes may be cool and they may not grieve, and that they should be pleased" This is in reference to a situation in which Muhammad's wives were grumbling about his preference for sleeping with a slave girl (Mary the Copt) instead of them. Accordingly, Muhammad may sleep with whichever wife (or slave) he wishes without having to hear the others complain... as revealed in Allah's literal and perfect words to more than a billion Muslims.
