Today, with the astonishing expansion of virtual space, we face the widespread injection of doubts into the public consciousness. The mass production and extensive dissemination of doubts, in many cases, leaves audiences defenseless against these doubts and deprives them of the ability to critique the formal and substantive fallacies embedded within them. Doubts circulated in virtual space against Islam and Shiism predominantly contain foundational, methodological, and argumentative flaws, yet the vast majority of audiences lack the capacity to identify these flaws. The present doubt is one of thousands that have been constructed, developed, and disseminated on the virtual pages of adversaries in recent days. This paper attempts to critique the doubt in question and demonstrate its various flaws, while also familiarizing readers with methods of doubt critique. In this research, data were collected through library resources and examined using a descriptive-analytical approach. This research demonstrated that all propositions contained in the present doubt, which were formulated with the objective of undermining Islam and Islamic societies and attributing the historical problems of Islamic countries to religion and Islam, constitute a collection of false and unsubstantiated claims. The authors of these doubts have attempted to validate their incorrect assertions through mere claims rather than scientific reasoning.
