Besides his leadership of the Kilab and influence over the Tayy and Kalb in Syria, Salih's influence also extended to tribes in the Jazira, including the Numayr. When two Numayri emirs lost Edessa to Nasr al-Dawla, the Marwanid emir of Mayyafariqin, they appealed for Salih's intervention; accordingly, he persuaded Nasr to restore Edessa to the Numayr. Furthermore, the Banu Munqidh first emerged as a political force in the Orontes valley under his patronage in 1024/25. At that time, Salih awarded the Munqhidi chieftain Muqallad ibn Nasr ibn Munqidh the feudal lands around Shayzar as an "iqṭāʿ" for supporting his conquest of Aleppo, but the town of Shayzar itself was controlled by the Byzantines.
