Deir Hanna
Bi'ina, which was also fortified, withstood a siege by Zahir in 1739, but Zahir later married the daughter of Bi'ina's "mukhtar" (headman), and thus brought Bi'ina into his domain. He also acquired the fortress of Suhmata through diplomatic means, further solidifying his rule over northern and eastern Galilee. In 1740, Zahir made an agreement with the neighboring Bedouin tribes to end their looting raids in the area. By then, Sa'd had taken control of Deir Hanna and Muhammad ibn Ali captured Shefa-'Amr, entrenching the presence of the Zaydani clan in western Galilee. After negotiations, Muhammad al-Naf'i, the "multazim" of Safad, surrendered the city to Zahir. Safad was the administrative seat of the "sanjak" and situated on a strategic hill overlooking the Galilee countryside. Zahir later acquired the fortified village of Deir al-Qassi after marrying the daughter of its sheikh, Abd al-Khaliq Salih.
