Explanation of the Obstacles to Declension: "Al-Adl"

The Shaykh : Al-Adl, al-Adl. The grammarians say: this means that the obstacle in it is al-Adl, al-Adl. That is, when something is changed from one thing to another, it is changed from one thing to another, meaning from one measure to another. It can be a proper noun and it can be a descriptive adjective. Al-Adl occurs in proper nouns and in descriptive adjectives. That is, it occurs in proper nouns, so the obstacle to declension is being a proper noun and al-Adl. And it occurs in descriptive adjectives, so the obstacle to declension is being a descriptive adjective and al-Adl. We have moved on from the measure of the verb, my son, be quiet. Okay, its example in proper nouns: 'Umar. We always read 'Umar, and 'Umar ibn al-Khattab, 'Umar ibn al-Khattab. Why did we say 'Umar? Because it is a name that is not declined. What is the obstacle to its declension? Being a proper noun and al-Adl. What is al-Adl? They said: because the original form of 'Umar is 'Aamir. 'Aamir, so it was changed from 'Aamir to 'Umar, from 'Aamir to 'Umar.
So, being a proper noun and what? And al-Adl. Okay, there is a star called Zuhul. Zuhul is the highest of the seven planets. Zuhul. So you say: I looked at Zuhul, or Zuhul.
The student: Zuhul.

The Shaykh : I looked at Zuhul. Why? Because it is a proper noun changed from Zahil, from Zahil, so it became prohibited from declension due to being a proper noun and al-Adl. And according to the words of the earlier astronomers:
"Zuhul bought Mars from the Sun *** So the moons competed in Mercury"
It is a descending order. It is recited for us by Hidayat Allah. It is recited for us. Okay.
"Zuhul bought Mars from the Sun *** So the moons competed in Mercury"
It says: descending order. Zuhul is the highest. It bought Jupiter, Mars, from the Sun, the Sun. So the moons competed here, Venus, in Mercury, Mercury, the Moon. The Moon is the lowest, the lowest of the seven planets. Okay, we said that al-Adl occurs in proper nouns, so you say: what is the obstacle to declension? Being a proper noun and al-Adl. And it occurs in descriptive adjectives, so the obstacle to its declension is being a descriptive adjective and al-Adl. Okay, its example: Ukhra. Ukhra. This is changed from al-Ukhra, changed from al-Akhir. Allah the Exalted said: Speak with it moving and He did not say: a number of days of Ukhra, Ukhra in the genitive case, in the genitive case, because it is a descriptive adjective for days, and days is in the genitive case by the preposition. But He says, Mighty and Majestic: The obstacle to declension is being a descriptive adjective and al-Adl, being a descriptive adjective and al-Adl. Okay, it is changed from what? They did not say from al-Akhir, they said it is changed from al-Ukhra. Its original form is alif-lam, so Allah knows best. Did it return? Is it this one, or is it changed from al-Akhir? Okay, in any case, they say: Ukhra is prohibited from declension. What is the obstacle to its declension? Being a descriptive adjective.
The student: And al-Adl.

The Shaykh : And al-Adl. Okay, and from that, meaning from being a descriptive adjective and al-Adl: Muthna, Thulatha, and Ruba'. Allah the Exalted said: Wings. In the genitive case by what?
The student: By the genitive construction.

The Shaykh : By the genitive construction, but it is in the genitive case, and the sign of the genitive case is the kasra. Wings, Muthna, Thulatha, and Ruba'. Thulatha and Ruba', Muthna and Thulatha. This is a substitute, a substitute that is conjoined. And despite that, it is in the nominative case because it is not declined. What is the obstacle to its declension? Muthna, Thulatha, and Ruba'?
The student: Al-Adl and being a descriptive adjective.

The Shaykh : They said: Being a descriptive adjective and al-Adl, being a descriptive adjective and al-Adl. How is it being a descriptive adjective and al-Adl? Yes, being a descriptive adjective because Muthna is a descriptive adjective, Thulatha likewise, and Ruba' likewise. From what was it changed? They said: Muthna is changed from two, two. Thulatha from three, three. Ruba' from four, four. So the obstacle to its declension is being a descriptive adjective and what?
The student: And al-Adl.

The Shaykh : And al-Adl, being a descriptive adjective and al-Adl.
