A heavy, full “s” — the back of the tongue is raised so the mouth sounds full.

Tip of the tongue near the lower front teeth

The tip rests near the lower front teeth, leaving a very narrow channel so the air whistles.

Same place as س, but lift the back of the tongue and press the middle up toward the palate.
