AL-WAKEEL-The Trustee, The Disposer of Affairs The Universal Trustee

The One who can be entrusted with all affairs. He is the ultimate Trustee, guardian and administrator of all things and we can trust in the fact that Al-Wakeel will provide the perfect resolution for every matter. The One who gives the satisfaction and is relied upon.
Allah, Exalted be He, says, “Enough is Allah as a disposer of affairs.” (Surat An-Nisaa”, 4:81) He also says, “You have made Allah your guarantor.” (Surat An-Nahl, 16:91)
Al-Wakeel means He is the disposer of affairs of all His creatures, the One who takes it upon Himself to provide for them, grant their requests, fulfil their needs, and the One who controls life and death and assists and protects those who seek His refuge.
He is also the One who takes care of His righteous servants’ affairs by guiding them to all that is easy, and keeping them away from all that causes them hardship.
Al-Kafeel means the witness, the guardian, the protector and the guarantor.

Benefits of belief in these names include the following:
