Rails query and order with same array used for query

I have method

def self.get_ayahs_by_array(ayahs_keys_array)
  self.where(ayah_key: ayahs_keys_array)
end

Which does a query on the Quran::Ayah model. ayahs_keys_array is an array of keys (primary_key) in a certain order. The query returns a different order, but I want it to return as the same order as the queried array.

Example: ayahs_keys_array is [5,4,1,2,7] and I want it to return in THAT order and not [1,2,4,5,7]

Any ideas?
