All those addressing the fervour that promoted the killing work of the Zahran Hashim jihadist network in Sri Lanka in April 2019 must come to grips with the modern currents of Wahhabi political thinking that go back to the outpourings of the Egyptian intellectuals Sayyid Qutb[1] and Al-Zawahiri[2] in the latter half of the 20th century. This step will then take investigators to the Al-Qaida movement[3] and thence to the more recent brand of Wahhabism embodied within ISIS.
