Dhu Nuwas
These killings destroyed the trade of Yemen with Europe and involved Dhu Nuwas in a war with the heathen King Aidug, whose commercial interests were injured by these killings. Dhu Nuwas was defeated, then he made war against the Christian city Najran in Yemen, which was a dependency of his kingdom. After its surrender, he offered the citizens the alternative of embracing Judaism, under coercion, or being put to death. As they refused to renounce their faith, he executed their chief, Harith ibn Kaleb, and three hundred and forty chosen men.
