So far, many claims and researches have been made about the authenticity of Zahabiya genealogy, some of which are mentioned here:[77][78][79][80] Attribution of the Zahabiya order to The Fourteen Infallibles: The followers of the Zahabiya order believe that the origin of this sect is reach to Imam Reza (8th Imam of Shiites) through Ma'ruf al-Karkhi. Imam Reza also leads to the Holy Prophet Muhammad (prophet of Islam) through his ancestors.[81][82] Ma'ruf al-Karkhi was from Karkh of Baghdad and one of the famous mystics. He born 750–60 CE and died according to many researchers, in the year 815 CE (200 AH).[83][84][85][86] Elsewhere it is said about him: The height of his perfection was such that fourteen sect branched out from him, which are known as the Marufiyah sects.[87] The disagreement that exists about Ma'ruf al-Karkhi is his connection and meeting with Imam Reza and his converting to Islam; Some believe that he met with Imam Reza and converted to Islam by him; Ibn al-Husayn al-Sulami claims in the book Tabaqat al-Sufiah that Ma'ruf al-Karkhi converted to Islam through Imam Reza.[88][82] Ali Hujwiri writes: Ma'ruf al-Karkhi converted to Islam by Imam Reza and was very dear to him.[89] Ibn Khallikan in the book Wafyat al-A'yan, in addition to mentioning Ma'ruf al-Karkhi converting to Islam by Imam Reza, has considered him as one of the Imam's patrons.[90] According to some sources, after Ma'ruf al-Karkhi became a Muslim and returned to his parents, who were Christians, they also converted to Islam.[91] Elsewhere, Ma'ruf al-Karkhi has been introduced as the special gatekeeper of Imam Reza.[92] It is also said about the cause of Ma'ruf al-Karkhi's death: After converting to Islam, he was the gatekeeper of Imam Reza.
