Belief refers to the value of a transcendent being and creator, while faith refers to the trust, submission and devotion of human beings to their creator. Faith is a dynamic concept that manifests itself in different ways according to each individual’s sociocultural environment, living conditions and educational background. Therefore, knowledge of faith also varies from individual to individual. The fact that people are born in different family environments, assume diversified professional and social roles, and the quality of the formal or informal education they receive directly affect the level of religious knowledge they have. In order to investigate this effect, this study focuses on the religious knowledge of individuals over the age of 60 residing in Ankara. The study aims to examine the sources of knowledge about the Islamic faith, the level of knowledge and the effects of this knowledge on the daily lives of individuals over the age of 60 living in Ankara. The findings to be obtained in line with these objectives are important in terms of contributing to the understanding of the religious knowledge acquisition habits of elderly individuals living in Ankara at the social and cultural level. In this study, semi-structured interview technique, one of the qualitative research techniques, was used. The population of the study consists of individuals over the age of 60 residing in Ankara. This population includes individuals from different socioeconomic levels and educational backgrounds. The research aims to provide in-depth information on the source and level of religious knowledge by focusing on the processes of acquiring religious knowledge by individuals in this age group. The sample of the study consists of 12 individuals over the age of 60 with different educational levels, occupational groups, gender, socioeconomic status and residing in Ankara. The study was conducted within the framework of the population and the sample and is limited to individuals over the age of 60 who have the experience of obtaining religious knowledge living in Ankara. In addition, this research is limited to the findings obtained from the interviews with the participants. The study is also limited to a specific time period. In this study, the age parameter was kept particularly high and the sample was selected from middle-aged individuals (60+). Although the participants were of similar ages, their occupations, education levels and family environments differed; this diversity is among the main reasons for the differentiation in religious knowledge sources and knowledge levels. In the study, the participants’ level of knowledge about faith and the sources they consulted were examined under thematic headings in line with the research questions; qualitative data were analyzed using descriptive analysis method. The data obtained were interpreted in relation to the demographics of the participants, and the levels of knowledge that differed due to the effect of the variables mentioned drew attention. The findings of the study show that the majority of the participants have knowledge of these basic principles of faith, but this knowledge is generally based on traditional, oral and practical bases acquired during childhood. At the same time, it also reveals that religious knowledge shapes the world of meaning in both individual and social dimensions in older individuals and directs their relationship with life.
