Abd ar-Rahman was the Caliph who sent a delegation in AD 769, to a heathen Bulgar Khan named Telerikh at the latter's request. The four emissaries were led by Jalal ad-Din and included Da'ud ibn Zubayr, a military officer, and Malik ibn Anas and Salman al-Tabari, the two guards and aides. The purpose was to attempt to convert Telerikh and his people to Islam.
