Bukhari

Hadith Commentary:
(1)
This sweat will be personal to each individual, reaching up to half of their ears. On the Day of Resurrection, due to continuous fear and terror, the nearness of the sun, and the crowding of people, this sweat will occur.

(2)
In view of people’s deeds, this sweat will be more or less, as is evident from the following hadith: On the Day of Resurrection, the sun will come extremely close to the people until they will be drenched in sweat. For some people, the sweat will reach up to their ankles, for some up to the middle of their shins, for some up to their knees, for some up to their thighs, for some up to their waists, for some up to their shoulders, and for some up to their mouths, and for some, it will bridle their mouths. The Prophet sallallahu alayhi wa sallam pointed towards his mouth with his hand. And some people will be submerged in sweat; the Prophet sallallahu alayhi wa sallam clarified this by striking his hand on his head. (Al-Mustadrak lil-Hakim: 4/615)

Hadith Commentary:
In one narration it is stated:
"On the Day of Resurrection, the sun will come close to the people by the distance of a mile, so the people will be in sweat according to their deeds.
This sweat will reach the ankles of some, the knees of others, the waist of some, and for some it will be like a bridle—
that is, the sweat will reach up to their mouths."
(Sahih Muslim, Kitab al-Jannah wa Sifat Na‘imiha wa Ahliha, Hadith: 7296. (2862))

Hadith Commentary:
Vocabulary of the Hadith:
(1)
Fawasiq:
This is the plural of "fasiq." The meaning of "fisq" is to go out, to exit. The reason these animals are called "fasiq" is that they are excluded from the general ruling of prohibition of killing other animals, or they are excluded from the ruling of permissibility (halal), or they are distinct from others in causing harm, spreading corruption and mischief, and in being of no benefit.

(2)
Al-Kalbu al-‘Uqur:
"‘Uqur" means one that tears apart, that wounds. Therefore, according to the majority of scholars, this refers to all predatory animals—cheetah, wolf, lion, etc., all are included in this. According to the Hanafis, it refers specifically to a biting dog.

(3)
Al-Ghurabu al-Abqa‘:
"Abqa‘" means one whose belly and back are white.

Benefits and Issues:
1.
The restriction to five (animals) is not for limitation, because in some narrations there are four, in some five, and in some six. For example, the mention of "‘aqrab" (scorpion), and in some narrations "as-sab‘u al-‘adi" (the attacking beast) is mentioned.

2.
According to Imam Malik rahimahullah, the reason for the permissibility of killing these animals is their harmfulness and corruption; therefore, any animal that is harmful, its killing is permissible. According to Imam Shafi‘i rahimahullah, the reason is their inedibility, i.e., their not being fit for consumption. Therefore, according to the Shafi‘is, animals are of three types:
1.
Those whose killing is recommended—these are the animals that are harmful.
2.
Those whose killing is permissible—these are the ones in which there is both benefit and harm, or neither benefit nor harm. However, eating them is not permissible.
3.
Those whose eating is permissible—their killing is not permissible; if a muhrim (person in the state of ihram) hunts them, he will have to pay a penalty (fidya).

According to the Hanbalis, any animal that attacks a human or causes harm, the muhrim can kill it.

According to ‘Allamah Ibn Qudamah, the restriction of "abqa‘" with the crow is coincidental; therefore, every crow may be killed.

According to the Hanafis, only the killing of these five animals is permissible; for the killing of others, fidya will be required. And according to the Hanafis, "zaagh," i.e., the agricultural crow that eats grain, its consumption is permissible.

The day when people will stand before the Lord of all the worlds.

Benefits and Issues:
➊ On the Day of Resurrection, the sun will be very close. Because of this, there will be a lot of sweating. However, this sweat will be more or less according to each person's sins.

➋ Some righteous people will be under the shade of the Throne (‘Arsh). At that time, there will be no shade except the shade of the Throne.

➌ The details of those who will attain the honor of the shade of the Throne are mentioned in a hadith as follows: a just ruler, a youth who remains engaged in the worship of Allah, one who loves the mosques (i.e., one who is devoted to prayer), one who loves a believer solely for the sake of Allah’s pleasure, one who rejects the invitation to immorality and thus protects his chastity, one who gives charity secretly, and one who remembers Allah in solitude and, expressing humility and meekness before Allah, sheds tears. See: (Sahih al-Bukhari, Book of Zakat, Chapter: Giving Charity with the Right Hand, Hadith 1423)
