The marriage of Prophet (s.a.w) to Aysha (r.anha) was decreed by Allah through inspirational dreams that the prophet saw. The dreams of the prophets are wahy', and wahy' is a divine command, similar to the command given to prophet Ibrahim (a.s) to slaughter his son Ismail (a.s). The fact that Aysha (r.anha) was young with a brilliant inquisitive mind and powerful memory, to later on convey all what she'd learned from her noble husband (s.a.w) in general, and in particular his intimate relations and behaviors within household, are to be count among some wisdom of this marriage.
where is the evidence that Allah divinely revealed ayesha radiyallahu anha should be married to teh prophet SAW as this is by far the strongest reason for the acceptance of the marriage
