Is it true that the Prophet Benjamin is buried in Southern Lebanon?

Here are two issues related to Benjamin:

1. His Prophethood: It has not been definitively established that Benjamin was a prophet. Some scholars held the view that all of Jacob's sons were prophets, and that their actions towards Joseph occurred before their prophethood. However, the more prevalent and scrutinised opinion among scholars is that Joseph's brothers were not prophets, and that "the Tribes" (Al-Asbat) mentioned in the Quran do not refer to Jacob's direct sons but rather to his descendants, including those among them who were granted prophethood. Al-Suyuti, Ibn Taymiyyah, and others, cited as evidence for the negation of their prophethood that no prophet came to the people of Egypt before Moses, except for Joseph. If any of his brothers had been a prophet, he would have called the people of Egypt (to monotheism). Based on this, Benjamin's prophethood has not been established.

2. Location of His Grave: Some sources mentioned that Benjamin's grave is located in the village of "Dhahr Himar" between Nablus and Beisan, and also in the Beqaa Valley. However, this information cannot be definitively confirmed. There is no prophet's grave whose authenticity is agreed upon except that of the Prophet Muhammad, peace and blessings be upon him. Umar ibn al-Khattab ordered the concealment of Daniel's grave to prevent shirk (polytheism).
