Ma'dikarib Ya'fur (Arabic: معد كرب يعفر) also romanized as Mu'di Karab Ya'fir, was a Himyarite king who ruled in the 6th century CE.
One of these inscriptions, found in Najd, gives Ma'dikarib Ya'fur the full title of King of Saba', Dhu Raydan, Hadramawt, Yamnat and their Arabs, on Tawdum and Tihamat.
[3] In 521 CE, the Lakhmid king, al-Mundhir III ibn al-Nu'man invaded parts of South Arabia, which forced the Arab tribes living in the affected areas to plead for help from Ma'dikarib Ya'fur.
[5] Ma'dikarib Ya'fur suffered a financial crisis during his reign and was forced to borrow a loan of money from a Christian merchant who lived in Najran.
[8] The historians Franz Altheim and Ruth Stehl, in their work Die Araber in der alten Welt, proposed that Ma'dikarib Ya'fur was only the regnal name taken up by Dhu Shanatir when he ascended to the throne.
