Abstract. This paper tries to propose a new concept that combines the concepts of knowledge management and religiosity. A new concept called Islamic Vanguard Spirit (IVS) is the result of the synthesis of knowledge management, manifest needs theory, social capital, and Islamic value. This new concept is based on the phenomenon of individualist salespeople and the neglect of religious values in sales activities that ultimately have an impact on sales performance that is not optimal. This concept promotes team collaboration as a lever of sales performance. The resources possessed by each individual are integrated into a team strength that complements and strengthens through knowledge sharing and knowledge donating activities. Through the spirit of doing the best, continuous improvement, asking others and helping others as IVS dimensions are expected to be able to increase selling performance. Testing the validity of each dimension is needed, which can then be empirically tested by adding several variables such as customer-oriented team, team-oriented leadership and adaptive selling capability.
