Allaah has created different types of jinn. Among them are some who can take on different forms, such as dogs and snakes; some who are like flying winds with wings; and some who can travel and rest. Abu Tha’labah al-Khushani said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘The jinn are of three types: a types that has wings, and they fly through the air; a type that looks like snakes and dogs; and a type that stops for a rest then resumes its journey.”
