This study aimed to investigate the values of Islamic spiritual leadership applied at Baitul Mal wat Tamwil (BMT) Usaha Gabungan Terpadu (UGT) Sidogiri Indonesia and how it motivated and inspired the employees through the establishment of vision and culture based on Islamic values that affect their working productivity and commitment. This study was based on a post-positivist paradigm, and it was a single case study. Indepth interviews were applied for a data collection which was obtained from several research informants. These interviews were recorded, then transcribed to be analyzed using an interactive model. The results showed that spiritual leadership at BMT UGT Sidogiri Indonesia was based on three bases; they are Iman (faith to Allah), Islam and Ihsan (ethic). The value of Iman was reflected through the working seriously, discipline, always supervised, accompanied, and protected by Allah. Next, the value of Islam was reflected through the commitment of doing congregational prayers (salat al-jamaah). An Individual who has an outstanding religious commitment will not forget religious ethics such as being discipline, honest, virtuous, not arbitrary to others and responsible for the job. Furthermore, the value of Ihsan was reflected through working culture. This culture was taken from the personality characters of Prophet such as shiddiq (honest), amanah (trustworthy), tabligh (deliver), and fathonah (intelligent)
