In Islam, the term "Holy Lineage" holds a special religious significance, particularly within the Shia sect.
Shia Muslims believe that the "Holy Lineage" refers to the direct descendants of the Prophet Muhammad. Specifically, this includes:
Shia Muslims hold the Holy Lineage in the highest regard, believing that they are the rightful successors and leaders of Islam.
Sunni Muslims also respect the Holy Lineage, but their definition and the status of these figures differ from that of the Shia. Some Sunni scholars include the Prophet’s wives as part of the Holy Lineage.
In some Islamic cultures, the term "Holy Lineage" is used to refer to individuals who are believed to be descendants of the Prophet Muhammad or as an honorary title.
