By the magic of Google -An ifrit is an enormous winged creature of smoke, either male or female, who lives underground and frequents ruins. Ifrits live in a society structured along ancient Arab tribal lines, complete with kings, tribes, and clans. They generally marry one another, but they can also marry humans
I live in the middle east and there are a lot of stories about them. Tales of 1001 Arabian Nights is rife with them.
Now one story i heard was was a bout a Djinn (the post about ifrits being associated with fire is accurate, also ifrits of the air too...) anyway, this guy who is saudi started talking about a Djinn he encountered...a human that was running at about 140 km/ph right along side his drivers side window as he was driving.
He was sweating and kinda shaky telling the story so i believe that he believed it....
Anyways, thats everything i know about Ifrits and Djinn
