AL-QĀDIR
Al-Qadir means the possessor of absolute power and might, who uses His power and might with His will, who does not overcome to His power but keeps it under control. It means using His absolute and infinite power with His absolute and infinite will.
Al-Qadir does not mean always displaying His power. On the contrary, it means having the power to choose whether or not to display His infinite power. The truly Al-Qadir is the one who can control His own power. Five of the seven verses containing the name Al-Qadir concern the resurrection in the hereafter.
Do they not see that Allah, Who created the heavens and the earth, and was not wearied(tired) by their creation, is Able to give life to the dead. Yes, He surely is Able to do all things.(The All-Capable)
The reason Allah, the All-Capable, does not do these things is not because He lacks the power, but because He feels compassion and mercy for humanity.
AL-QADĪR(AL-QADEER)
It means the One who has power over everything, who determines a measure (destiny) for everything, who appreciates the value of everything, who does not create anything without measure, limit, or meaning, and who uses His unique and unparalleled power to determine the measure and value of His creations. It appears 44 times.
Do they not travel through the earth, and see what was the End of those before them,- though they were superior to them in strength? Nor is Allah to be frustrated by anything whatever in the heavens or on earth: for He is All-Knowing. All-Powerful. (The Omnipotent)
AL-MUQTADIR
The absolute possessor of power, the head of all authority. It means the unique and unparalleled subject with infinite power, who does not bow down to the power of any authority, who confronts every authority but whom no authority can confront.
And cite for them the parable of the present life: it is like water that We send down from the sky; the plants of the earth absorb it; but then it becomes debris, scattered by the wind. Allah has absolute power over everything. (The Supreme Determiner / The All-Dominant)
AL-QAHHAR
It means the ever-victorious, the ever-subduing, the one who crushes those who defy Him, the one who makes everyone submit to His unique and unparalleled authority, the one whose power is absolute and infinite.
Say, “Who is Lord of the heavens and the earth?” Say, “Allah.” Say, “Have you taken besides Him lords who can neither benefit nor harm themselves?” Say, “Are the blind and the seeing equal? Or are darkness and light equal? Or do they assign to Allah associates, who created the likes of His creation, so that creations seem alike to them?” Say, “Allah is the Creator of all things, and He is The One, the Irresistible(the Subduer).”
AL-MATIN
It means very firm, very steadfast, uniquely unparalleled, tough, having limitless endurance, maintaining its steadfastness in all situations.
Verily, Allah is the All-Provider, Owner of power, the Most Strong(the Steadfast, Firm).
