Do other intelligent beings exist in some other planet besides man according to Quran or Hadith?

Does Quran or Hadith mention any other intelligent beings in the universe like humans maybe on some other planet? Except for Jin and Angels which are mentioned in Quran. Prophet (P.B.U.H) was given the title of Rehmat-ul-Alamin. And generally the word Alamin is used for man, jin, angels and everything else. How does that fit with the theory of existence of any other being on any other planet?
