Is it permissible for a Muslim to ask Jewish rabbis about matters related to the universe and creation, without believing or disbelieving them, following the example of the Prophet's—peace and blessings be upon him—questions to some rabbis, and Umar's questions to Ka'b al-Ahbar?

A Muslim must believe that the Qur'an and Sunnah are sufficient for all that a servant needs in matters of their religion and worldly life. There is no need to ask the People of the Book about religious matters, and it is forbidden for a layperson to read their previous scriptures. It is permissible for scholars to ask them for consideration or to establish a proof against them, but not for confirmation. The Prophet, peace and blessings be upon him, questioned the Jews, and Umar ibn al-Khattab questioned Ka'b al-Ahbar, but their questioning was not an admission of the validity of their answers. Rather, it was to test information and expose falsehood. The Prophet, peace and blessings be upon him, disbelieved the Jews in some of their answers, and Umar corrected Ka'b in what he said. Among the Isra'iliyyat (narrations of Israelite origin), some are not known to be true or false. As for asking them about cosmic scientific matters, they have no specialization in that. Their knowledge and concealment of what is in the Torah does not mean they possess knowledge of cosmic truths based on experimentation.
