Al-Wakil

Wakil is the Arabic word for an advocate, agent, and a trustee. The latter meaning, along with the name Disposer of affairs, is used as one of the names of God in the Qur'an. Al-Wakil is usually considered the 52nd or the 53rd name of God and it is mentioned in Qur'an multiple times. In Islam, God is considered the supreme trustee, who can be relied upon to manage all of the affairs perfectly.
The root w-k-l bares meanings of entrusting, assigning, and empowering; some of the other words that are made from this root are توكل and وكالة.
