On April 23, Saad al-Durihim, a Saudi Wahhabi sheikh, posted a tweet on Twitter in which he said that jihadist fighters in Iraq should adopt a "heavy-handed" approach and kill any Shiites they can get their hands own, including children and women. This is so that the "rawafid" — a term used by Wahhabi Salafists to refer to Shiites — will fear them.
This tweet sparked sharp criticism on Twitter. Many considered it to be incitement to murder and contrary to the tolerance of Islam, which forbids the killing of women and children in battle, even those of infidels and polytheists.
