[1] Two years later, in 472 CE, Sharhabil Yakkuf shared the royal title King of Saba', Dhu Raydan, Hadramawt, Yamnat and their Arabs, on Tawdum and Tihamat with his three sons, Lakhni'ah Yanuf, Ma'dikarib Yun'im, and Abu Shamir Nawaf.
Due to his name in inscriptions lacking a patronymic, he is believed by historians to be completely unrelated to the descendants of Dhamar Ali Yahbur II, hence he was the founder of a new dynasty to rule over Himyar.
[6][7] During his expeditions across the peninsula, he built a chain of synagogues across the trade routes from South to East Arabia which were not only meant for the purpose of worship, but for the Himyarite kings to transmit messages back to their palace; similar to a post office.
[8] In the year 474 CE, Sharhabil Yakkuf and his three sons carried out a major campaign to the north of the Arabian Peninsula, in order to stop the attacks from rebellious Arab tribes which included branches of the Tayy and Abd al-Qays.
[9] According to several Ethiopian sources including those in the Ge'ez script, a missionary named Azqir arrived in Najran during the rule of Sharhabil Yakkuf to spread the message and religion of Christianity.
