Burayha was among the leading personalities of the Christians and among their brilliant scholars. He looked for the truth and sought guidance, so he associated with all the Muslim sects; he debated with them but did not reach the objective he wanted. The Shi’ites and Hisham b. al-Hakam were described to him, and he along with a hundred Christian scholars. When they sat down, Burayha questioned Hisham about the most important ideological and theological matters. Hisham answered them, and then they all went to have the honor of meeting with Imam Abi ‘Abd Allah (al-Sadiq), peace be on him. Before they met him, they had met with Imam Musa, so Hisham told him about his debates and speech with Burayha. Thus, the Imam turned to Burayha and asked him:
-O Burayha, what about your knowledge of your Book?
-I am knowledgeable of it.
-What about your trust in the explanation on it?
-Just as I have knowledge of it.
Then, he, peace be on him, recited to him the Bible and read to him its chapters. When Burayha heard of that, he believed that the religion of Islam was true, that the Imam was of the Prophet’s Tree, and he said to him: “I have sought you or the like of you for fifty years.”
Then he and his wife became Muslims; they went to Abi ‘Abd Allah (al-Sadiq), peace be on him, and Hisham told him that they became Muslims at the hand of his son Musa, peace be on him. Imam al-Sadiq, peace be on him, became pleased, turned to Hisham and said to him: “Offspring, one of the other.”
Burayha asked Abi ‘Abd Allah (al-Sadiq): “From where have you brought the Torah, the Bible, and the Books of the prophets?”
“We have them,” replied the Imam, “we have inherited them from them; we read them just as they had read them; we say them just as they had said them; surely Allah does not appoint over the earth a proof who says that he does not know when he is asked.”
Burayha associated with Imam Abi ‘Abd Allah (al-Sadiq) and was among his most loyal companions. When the Imam moved to the Abode of Everlastingness (lit.passed away), Burayha associated with Imam Musa till he died during his lifetime. ( Bihar al-Anwar, vol. 4, p. 147)
