What is the ruling on using genetic fingerprinting or genetic analysis to determine family origins or affiliation with a specific tribe if the lineage is unknown, and are the results of the analysis to be adopted whether they align with or contradict previous expectations?

Genetic fingerprinting is not a means of establishing or verifying lineages except in specific cases, such as disputes over unknown parentage or suspicion regarding a child's lineage. The Islamic Fiqh Academy has ruled that it is not permissible to rely on it to disown lineage or to prioritize it over li'an (oath of condemnation), nor is it permissible to use it to confirm the validity of lineages that are already legally established. However, it is permissible to use it in cases of dispute over unknown parentage, suspicion regarding newborns, and the loss or mixing up of children. It is recommended that the state prohibits genetic fingerprinting examinations unless requested by the judiciary, and that a special committee for genetic fingerprinting be formed, comprising religious, medical, and administrative specialists, to oversee the results. Ascertaining distant family lineages is not among the circumstances that permit the use of genetic fingerprinting.
