And a third example: "Al-Rahman" is one of the names of Allah the Exalted, encompassing complete mercy, about which the Messenger of Allah (peace and blessings be upon him) said:

The Shaykh :"And a third example: Al-Rahman, one of the names of Allah the Exalted" No one else is named by it, so even if someone tries to take the name Rahman, Allah the Exalted will make him taste humiliation, like the man of al-Yamamah who took this name, but he became the most humiliated and most wretched of Allah's servants.
"One of the names of Allah the Exalted, encompassing complete, vast mercy" Complete in its type, vast in its scope, complete.
"About which the Messenger of Allah (peace and blessings be upon him and his family) said:

Allah is more merciful to His slaves than this lady to her son.

لله أرحم بعباده من هذه بولدها

Sahih al-Bukhari 5999

" The "lam" in "Lillah" is the lam of inception, which is the lam that enters the subject for emphasis. So, if I say "Layyidun qaim" (Zayd is standing), it is more emphatic than if I say "Zaydun qaim" (Zayd is standing). This lam is for emphasis. If another particle comes that is more emphatic and clearer, it displaces it from its place, and it is said, "This is not your place, so go back" or "This is not your nest, so go back" If "in" (the particle of affirmation) comes, it displaces it. For example, if I say "Layyidun qaim," the lam is for inception and for emphasis. If "in" comes, you say "Inna Zaydan laqaim" (Indeed, Zayd is standing), and you do not say "Inna layyidun qaim," because the two emphatic elements do not meet in one place. Therefore, we move the lam to the predicate, and we say "Inna Zaydan laqaim."
"His saying (peace and blessings be upon him and his family):

" Know that some of the scholars (may Allah have mercy on them) are cautious about the word "A'lam" (the most knowing) in relation to Allah Mighty and Majestic. They interpret "A'lam," which is a superlative name, as "Fa'il" (the doer) with the name of the doer. Is this speech understood or not? Yes.
The student: Clear.

The Shaykh : Clear, meaning, for example, they say It is not "A'lam" in its proper sense, i.e., the superlative, but it means "Alim" (Knowing). Allah is Knowing. Why? They said that if you make it a superlative, you would equate the one who is preferred with the one who is preferred over, and this is not correct or sound. We say to them: Glory be to Allah! Which is more indicative of perfection: to say "Allah is Knowing where He places His message" or "Allah is the most knowing"? Which is it? "Allah is the most knowing," because it indicates that the knowledge of Allah is broader than the knowledge of others. But if you say "Allah is Knowing," this is a description shared by the Creator and the created equally. So look at how these corrupt minds distort the words from their places and fall into what is worse than what they fled from.
Here, for example, "Arahim" (the most merciful). "Allah is Arahim to His servants." He says, "You cannot say 'Arahim' is a superlative name. If you said so, it would necessitate that the one who is preferred and the one who is preferred over share the original attribute. So 'Arahim' means 'Rahim' (Merciful). Okay, which is more eloquent in perfection: to say 'Arahim' or 'Rahim'? 'Arahim,' without a doubt, because 'Rahim' equates the two sides.
In any case, whenever you encounter a superlative form (af'ala) attributed to Allah Mighty and Majestic, it is a superlative name, and it is on its proper basis, and it is better than what those people distorted, who make it a name of the doer.

" Meaning: A mother of a boy who found him among the captives, took him, pressed him to her belly, and nursed him. Allah is the Greatest. This mother was searching among the captives: "Where is my child? Where is my child?" When she found him, she took him as if she had no mind, pressed him to her belly, and nursed him. The Prophet (peace and blessings be upon him) said: This mercy is complete in terms of what? In terms of type.
