Nasif ibn al-Nassar al-Wa'ili (Arabic: ناصيف النصار; died 24 September 1781) was the most powerful sheikh of the rural Shia Muslim (Matawilah) tribes of Jabal Amil (modern-day South Lebanon) in the mid-18th century.
[2] Under his leadership, the Jabal Amil prospered, due largely to the revenues from dyed cotton cloth exports to European merchants.
However, by 1768, Nasif and Zahir entered into a close and durable alliance, with both parties benefiting in their cooperation against the Ottoman governors of Sidon and Damascus.
[5] Afterward, Nasif and Zahir's forces captured the city of Sidon, the capital of its namesake province, which included the Galilee and Jabal Amil.
[4] This victory marked the peak of Shia power in Lebanon region during the Ottoman era (1517–1917),[6] and according to de Tott, the Metawalis became a "formidable name [sic]".
In 1780, after having consolidated his hold over the Galilee and defeating Zahir's sons, Jezzar Pasha launched an offensive against the rural sheikhs of Jabal Amil.
