<![CDATA[This study aims to determine the effect of the Theory of Planned Behavior and knowledge of the intention to invest in the assembly of the Taklim Muhammadiyah Sub-District of Sukomanunggal Surabaya. Primary data retrieval in this study used a questionnaire with a sample of 40 taklim assemblies in Sukomanunggal sub-district, Surabaya. The characteristics of the sample in this study were the pilgrims who attended the recitation in the assembly of taklim Muhammadiyah, Sukomanunggal, Surabaya. The sampling technique is Non-Probability Sampling and Simple Random Sampling. This study uses a quantitative approach with multiple linear regression analysis. The endogenous variable in this study is the intention to invest, while the exogenous variable used is part of the Theory of Planned Behavior which consists of attitudes, subjective norms, and Perceived Behavior Control and Knowledge. The results of this study indicate that simultaneously and partially attitudes, subjective norms, Perceived Behavior Control, and knowledge have a significant effect on the intention to invest in the assembly of taklim members of Muhammadiyah, Sukomanunggal District, Surabaya. Suggestions for further research to add to the scope of research subjects so that more general information can be obtained about related research, and using other variables outside of this research variable because it should be suspected that there are still several other factors that can influence intention to invest.Keywords: Theory Of Planned Behaviour, Knowledge, Infaq, IntentionREFFERENCESAbd Al-Rahman Al-Jazairi, Al-Fiqh ‘Ala Al-Madzahib Al-‘Arba’ah, (Bairut: Dar Al-Kutub Al-Ilmiyah, 2003), Juz.
