AL-MUQTADIR-The Omnipotent The All Authoritative One

The One whose Might is Great and through His overwhelming Power Al-Muqtadir controls all His creatures. He subdues everyone and everything in His domain. His decree prevails in every situation. The One with the perfect Power that nothing is withheld from Him.
Allah, Exalted be He, says, “Say, ‘He is able to send punishment upon you from above you or from beneath your feet.” (Surat al-An’aam, 6:65). He also says, “Indeed, the righteous will be among gardens and rivers, in a seat of honour in the presence of a Sovereign who is Perfect in Ability.” (Surat Al-Qamar, 54:54-55). He also says, “Allah has power over all things.” (Surat Al-Baqarah, 2:20).
Allah is Al-Qaadir, that is, He is able to do whatever He wills and has power over everything. He is in no way affected by helplessness or weakness. Nothing in the heavens or the earth can ever frustrate His plan.
The name Al-Muqtadir (the Perfect in Ability) describes additional ability. The same thing can be said about the name Al-Qadeer (the Ever Able), which means the One whose ability is complete and perfect; He is the One who creates, manages all affairs, makes things in the best form, guides, sends astray, gives life, causes death, and the One who will resurrect all His slaves fo inal judgement, and He is able over all things.

Benefits of belief in these names include the following:

Truly relying on Allah, Glorified and Sublime be He, being totally attached to Him alone and having confidence that He is sufficient for us.
Being assured of Allah’s mercy, Exalted be He, recognizing His infinite wisdom, anticipating His graciousness when struck by all types of adversities.
Avoiding oppression in all its forms, especially oppressing Allah’s slaves, for Allah, Exalted be He, is able to support the oppressed and punish the oppressors.
Making use of whatever skills and ability Allah has given us in ways that are pleasing to Him and being careful not to use them in ways that are displeasing to Him, for He is able to take them from us altogether.
Not being deluded by our ability and recognising that there is no power or might except with Allah and thus turn to Allah alone for everything.

The One whose supreme power determines and delivers the suitable measure of all things. The One whose decisions always prevail. The One who has power and ability to ordain all things.

The One who is empowered to do whatever wisdom decides. The One who has the power and ability to decide the outcome of all matters.

The One whose power enforces all decrees and ordains the course of all affairs. The One whose decree prevails in every situation.

From the root q-d-r which has the following classical Arabic connotations:

to measure something, know the measure of something
to distribute, allot or apportion the suitable measure
to decree, to ordain, to decide a matter (as though measuring it to fit)
to exercise thought in preparing something, to make use of reason
to intend or determine something
to have the power to accomplish, to be rendered able
to be able to prevail, to be empowered

This name is used in the Qur’ān. For example, see 54:55

Qādir, from this same q-d-r root,  indicates the supreme ability to make a decree or ordain something, while Muqtadir points to the supreme power by which that decree is enacted.

That is, Muqtadir is an intensive form of the root q-d-r which emphasizes the use Supreme Power to actively enforce whatever Divine wisdom decides.

The Arabic prefix mu at the beginning of the word points toward the means by which something happens, or the embodiment of an action, leading to translations such as the one who is, or the one who does (similar to the suffix er in English).

Qādir is a less intensive form of the root q-d-r which describes the attribute of being able to decree, ordain, appoint or decide.
