It is a demonstrative noun, the lam indicates distance, the kaf is a particle of address, and it was used in the plural because the one being addressed is a group. Here, you must know that the demonstrative noun refers to the thing indicated, and the kaf refers to the one being addressed. So how do you say it if you address a male and point to a masculine thing? That. And how do you say it if you point to two things while addressing a male? Those two, because you are pointing to two things and addressing one person. What do you say if you point to one thing and address two people? That, correct. And what do you say if you point to one thing and address a group of women? That. Now, if you point to one thing and address a group of females?
The student: That.

The Shaykh : That is incorrect.
The student: Those two.

The Shaykh : You are addressing a group of females, pointing to one thing while addressing a group of females?
The student: Those.

The Shaykh : Those, correct? Be careful with the stress on "those"; pay attention to this so that the thing being pointed to does not get confused with the one being addressed. The demonstrative pronoun is based on the thing being pointed to, and the kaf is based on the one being addressed. Is that clear? Okay, pointing to a group while addressing a group of males, Muhammad?
The student: Those.

The Shaykh : Those is in the Qur'an:

And those - We have made for you against them a clear authorization.

وأولَئِكُم جعلنا لكم عليهم سلطانًا مُبِينًا

[An-Nisa 4:91]

. Okay, that's it. Pointing to two females while addressing two females, Abdullah? Those two, correct. Okay, in any case, there are many examples, but strive for precision. Is the most eloquent form of the kaf of address in the demonstrative pronoun to follow the one being addressed, or is it always the singular masculine, or is it the singular open masculine for the masculine and the singular closed feminine for the feminine? There are three opinions, and all are languages. That is, do we bind the kaf to one method of singular and open, saying: That, those, those? Or do we bind it to singular with open for the masculine and closed for the feminine? These are two views. Or do we say: it follows the singular masculine addressee with an open kaf, the singular feminine addressee with a closed kaf, the dual with a kaf accompanied by the dual marker, the group of women with a kaf accompanied by the women's nun, and the group of men with a kaf accompanied by the plural mim? The last one is the most eloquent, but the other two views are permissible. Allah the Mighty and Majestic says:

. The author said: " is the subject, is a substitute for it, is a description, and the predicate is ." This means that his saying: and what is conjoined to it or became its attribute is in the position of the subject, and is in the position of the predicate. Is it possible to consider another view? Yes, it is possible. We can make the subject, its predicate, and a second predicate. This view is stronger in meaning. That is: That is your assumption which you assumed about your Lord, meaning you did not assume anything else about Him and that He would not return you. Then he informed about this assumption with another predicate, saying: . This meaning is stronger than the author's (may Allah have mercy on him) saying that is a substitute for , that is a description of it, and that is its predicate. , and He is Allah the Exalted. He attributed lordship to them because they acknowledge the lordship of Allah and do not deny it. . And in another sevenfold reading: . means it destroyed you. So you became, meaning you turned into, among the losers. Here, if we look at the word "became" (asbaha) in its mere form, it indicates the morning, but it is used in the Arabic language to mean becoming. You say: He became knowing nothing, meaning he turned into one who knows nothing. And here, does not mean you entered the morning as losers, but the meaning is: you became among the losers. The loser is the opposite of the winner. And he said: , because these people who denied the resurrection lost both this world and the Hereafter in reality. Their worldly life will not benefit them, and in the Hereafter they are in the Fire, and this is the ultimate loss.
