The Oath of the Denier of Lineage and the Principle that People Are Trusted Regarding Their Lineages

The questioner:
He says: Honorable Shaykh, may Allah grant you success. In the words of the author (may Allah have mercy on him) in the previous lesson, it states that the one who denies a right belonging to a human being is required to take an oath in every case, except for lineage. Does this contradict the principle that people are to be trusted regarding their lineage?

The Shaykh:
What?

The questioner:
He says: Honorable Shaykh, may Allah grant you success. In the words of the author (may Allah have mercy on him) in the previous lesson, “The denier is made to take an oath in every right belonging to a human being, except for marriage, divorce, taking back a wife, and lineage.” Does this conflict with the principle that people are trusted regarding their lineages?

The Shaykh:
What is obligatory in this? People are trusted regarding their lineages. You compel a man to accept the lineage of a person he does not acknowledge. What is obligatory in this? And you say people are trusted regarding their lineages. Does this come from the claimant, or from the one against whom the claim is made? No, this is not acceptable. You do not attach a lineage to a person who does not acknowledge it and disowns it. You are attaching to him something that is not his.
