Müsahiplik
Musahiplik or Müsahiplik (roughly, "Companionship / Spiritual brotherhood") is a covenant relationship between two men of the same age, preferably along with their wives. In a ceremony in the presence of a dede the partners make a lifelong commitment to care for the spiritual, emotional, and physical needs of each other and their children. After the Hijra, the Islamic prophet Muhammad instituted brotherhood between the emigrants, Muhajirun, and the helpers, Ansar, and he chose Ali as his own brother.[1] This early Islamic practice has survived and continued to exist only in the Alevi sect of Islam. This early Islamic practice ceased to exist in all other Islamic sects .
