Purpose – This study investigates the factors influencing Muslims’ intention to participate in green waqf in Indonesia. Specifically, it examines the role of knowledge within the Theory of Planned Behavior (TPB) framework to understand how knowledge, attitudes, subjective norms, and perceived behavioral control shape intention to become a waqif (a person who endows waqf).
Methodology – The research employs a quantitative design using survey data collected from 100 Muslim respondents in Indonesia. Data were analyzed with Structural Equation Modeling (SEM) using SmartPLS 3 to test the relationships among knowledge, attitudes, subjective norms, perceived behavioral control, and intention.
Findings – The findings reveal that knowledge positively influences attitude, and both attitude and perceived behavioral control significantly impact intention to become a waqif. However, subjective norms do not significantly affect intention.
Implications – This research contributes to the existing literature by extending TPB in the context of green waqf and offering insights into the role of knowledge in shaping attitudes toward green waqf. Practically, the study highlights the need for increased awareness and structured initiatives to enhance participation in green waqf, particularly through education and government-driven campaigns.
Originality – This research adds to the growing literature on green waqf by applying and extending TPB with knowledge, offering fresh insights into behavioral determinants of waqf participation and highlighting the link between Islamic philanthropy and environmental sustainability
