Editorial inference
The law asks for a binding commitment to truth, which a Muslim can make by oath or affirmation. (Our reasoning from the sources, not source text.)
Source checked ; human review pending
A court requires a commitment to truthful testimony, not conversion or acceptance of a particular scripture. Texas Constitution Article I, Section 5 says a witness is not disqualified because of religious opinion or the absence of religious belief. It permits oaths or affirmations in a form binding on the witness's conscience and preserves the consequences of perjury. [1]
Federal Rule of Evidence 603 likewise requires an oath or affirmation designed to impress on the witness the duty to testify truthfully. These provisions separate the seriousness of testimony from a ritual object: neither makes a Bible the prerequisite to truthful evidence. The federal rule does not govern every Texas state proceeding. [2]
This record does not decide how a particular judge will administer an oath, or guarantee the admissibility or credibility of testimony; competency, privilege and evidentiary rules remain relevant. It does not treat a sincerely chosen religious oath as improper. Ask the court about an appropriate oath or affirmation.
