Is the statement that a single report does not yield certainty correct, given the argument that a single report is not accepted in determining the end of the month of Ramadan?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Does the non-acceptance of a single report in determining the end of Ramadan confirm the statement of some jurists of the principles of jurisprudence that a single report does not yield certainty? This is despite the fact that it is well-established from the Prophet (peace and blessings be upon him) that a single report is accepted in many matters, which confirms the incorrectness of that statement. Thus, that statement would be a matter of precaution, or is there another explanation?

Answer:
This is not a single report; this is testimony. Testimony has specific requirements. In breastfeeding, the testimony of one woman is sufficient. In financial matters, the testimony of two men or one man and two women is sufficient. In retaliation and fixed punishments, the testimony of two men is required, and women are not included in the testimony for retaliation.
In the case of unlawful sexual intercourse, four witnesses are required. In unlawful sexual intercourse, four witnesses are required. In proving financial hardship, if a wealthy person claims hardship and there is no apparent reason for people to believe him, three witnesses are required. This is a matter of testimony, not a matter of reporting. It is a matter of testimony, meaning that proving the breaking of the fast in Ramadan is a matter of testimony regarding the sighting of the new moon, so two witnesses are required. Yes.
