Al-A'LA
It means the Absolutely Supreme (always supreme or the only supreme) and Exalted One.
1. Glorify the Name of your Lord, the Most High,
2. Who has created (everything), and then proportioned it;
3. and who determines the nature [of all that exists], and thereupon guides it [towards its fulfilment],
You cannot glorify anyone other than Allah by attributing Lordship to them, for Allah is the Supreme and Exalted One; you cannot debase Allah, for He is the Most High, the Absolute, the Limitless and Exalted, the Lord who is unparalleled and unique in His exaltation. No created being, not even their hand or mind, can reach His exaltation or bring Him down from His station. Whoever tries to do so debases themselves and distances themselves from Allah. It is the duty of every believer to glorify Him. Glorifying Him means acknowledging His transcendent and absolute nature. To glorify Him is for all beings, intelligent and unintelligent, to act according to the measure He has set for everything from creation and to fulfill the purpose He has ordained for everything from creation.
19. And have in his mind no favour from anyone for which a reward is expected in return.
20. Except only the desire to seek the Countenance of his Lord, the Most High;
AL-AHAD
Al-Ahad expresses the absolute and infinite, unique and unparalleled, limitless and infinite, boundless and limitless, countless and immeasurable oneness of Allah.
1. Say: “He is Allah, the One (Al-Ahad).
2. Allah, Who is in need of none and of Whom all are in need;(Al-Samad).
3. He begets not, nor was He begotten;
4. "And there is none co-equal or comparable unto Him."
In the universe, there is not a single being called, considered to be called, or capable of calling itself "Ahad." However, "Samad" is different. Arabs call their leaders, whom they have favored, "Samad." Therefore, "es-Samad" is used with the definite article. The message conveyed is: Allah's attribute of "Samad" is not like the attribute of "Samad" that you give to your leaders. However, the attribute of "Ahad" is used vaguely, because this attribute has never been used for any created being. Therefore, there is no possibility of confusion. For a being to be called "Ahad" would have to prove that they were born without parents, and that there is no other example of their kind. This is impossible except for Allah. This attribute is only used in a negative sense for a being other than Allah, and nothing else. Indeed, except for the one place in the Quran where it is used for Allah, the others are like this.
ES-SAMED
Es-Samed expresses that Allah is the absolute and infinite, unique and unparalleled support upon which everything rests and leans. The first cause and the ultimate purpose, the beginning without beginning and the end without end, far from decrease and increase, the absolute and complete meaning. The being to whom everything and everyone is in need, while He needs nothing and no one; the perfect and self-sufficient being who suffices for Himself and for everyone and everything.
1. Say: “He is Allah, the One (Al-Ahad).
2. Allah, Who is in need of none and of Whom all are in need;(Al-Samad).
3. He begets not, nor was He begotten;
4. "And there is none co-equal or comparable unto Him."
AL-WAHID
The name Al-Wahid means the One, the unique and unparalleled, the absolute and infinite, indivisible.
Say (O Muhammad SAW): "What thing is the most great in witness?" Say: "Allah (the Most Great!) is Witness between me and you; this Quran has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allah there are other aliha (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allah) is the only one Ilah (God). And truly I am innocent of what you join in worship with Him."
AL-HAK
It means the absolute and infinite truth, the absolute right, the unique and unparalleled source of truth, the being whose existence needs no proof. (The Truth)
Such is Allah, your Lord, the Truth. What is there, beyond the truth, except falsehood? How are you turned away?
AL-HASIB
It means the One who created existence with a reckoning, whose reckoning is above all reckonings, who sees the reckoning of His servants as unique and unparalleled, and who suffices for His servants.(The Reckoner)
When you are greeted with a greeting, greet in return with what is better than it, or (at least) return it equally. Certainly, Allah is Ever a Careful Account Taker of all things.
