The purpose of this research paper is to examine the adoption of Islamic banking (AIB) in the Bottom of the Pyramid (BoP) Market of Pakistan. The study used theory of planned behavior to hypothesize the relationship of the attitude (ATT), subjective norms (SN), perceived behavioral control (PBC), and Islamicity of the Product (IoP) on adoption of Islamic Banking (IB). Exploratory research design was used with a total of 400 questionnaires were distributed using a multi-staged stratified sampling (random sampling within each stratum) approach of which 320 usable questionnaires were returned representing 80 percent response rate. Partial Least Square Structural Equation Modeling (PLS-SEM) approach was used to analyze the hypothesized relationship of the conceptual framework. Results indicated that attitude (ATT), subjective norms (SN), and Islamicity of product (IoP) explained notable effect on the adoption of Islamic banking comparatively the perceived behavioral control (PBC). The overall effect of ATT, SN, PBC, and IoP explained 39.3 percent on AIB within the context of BoP. The adoption of Islamic banking counts the aforementioned variables with their countable effects. The inclusive outreach and features explaining the Islamicity of the financial products can enhance the span Islamic banking market share.
