Bukhari

Hadith Commentary:
The Battle of Uhud took place in 3 AH in the month of Shawwal, and in 11 AH, in the month of Rabi' al-Awwal, the Prophet (sallallahu alayhi wa sallam) passed away.
Therefore, the narrator's statement that it was "after eight years" cannot be correct.
The meaning is that it was in the eighth year, as we have clarified in the translation.
The farewell to the living is obvious, because this event occurred in the last year of his blessed life, and as for the farewell to the dead, its meaning is that now their visitation with the body will no longer be possible,
as used to happen in the world.
Hafiz Sahib has said that although the Prophet (sallallahu alayhi wa sallam) is alive even after his passing, that is an afterlife (akhirah) life, which does not resemble worldly life.
In the narration, there is mention of the honor of seeing the Prophet (sallallahu alayhi wa sallam) at the Pond of Kawthar (Hawd al-Kawthar).
There, all of us Muslims will have the honor of meeting you.
O Muslims! Strive so that on the Day of Judgment we are not ashamed before our Prophet (sallallahu alayhi wa sallam).
Help his religion as much as you can.
Spread the Qur'an and Hadith.
Those who harbor enmity towards the noble Hadith and the people of Hadith—who knows what face they will show to the Messenger of Allah (sallallahu alayhi wa sallam) at the Pond of Kawthar.
May Allah Ta'ala grant all of us the meeting with our Messenger (sallallahu alayhi wa sallam) at the Pond of Kawthar.
Amin.

Hadith Commentary:
➊
The Prophet (sallallahu alayhi wa sallam) passed away in Rabi' al-Awwal of the 11th year after Hijrah, after completing the Farewell Pilgrimage (Hajjat al-Wada') in the 10th year. The Battle of Uhud took place in the 3rd year after Hijrah. Therefore, the narrator's statement that the funeral prayer was performed for the martyrs of Uhud eight years after the Battle of Uhud cannot be correct; however, it is correct to say it was in the eighth year.

➋
The farewell to the living is obvious, because this event took place in the last year of the Prophet’s (sallallahu alayhi wa sallam) blessed life. As for bidding farewell to the dead, it means that now it will not be possible to visit them with the physical body as used to happen in this world.

➌
Hafiz Ibn Hajar (rahimahullah) states that although the Messenger of Allah (sallallahu alayhi wa sallam) is alive even after his passing, the life of the Hereafter is different from the life of this world.
(Fath al-Bari: 7/436)

➍
Since this hadith mentions the martyrs of Uhud, Imam Bukhari (rahimahullah) has narrated it, as if he has mentioned this hadith while interpreting the following verses:
“Do not think of those who have been killed in the way of Allah as dead. Rather, they are alive with their Lord, receiving provision.”
(Al Imran: 3:169)
Previously, we have already discussed the rulings and issues related to this hadith.
(Sahih al-Bukhari, Funerals, Hadith: 1344)

Hadith Commentary: Benefits and Issues:

Kaal-muwaddi‘ lil-ahyaa’i wal-amwaat:
It is as if you (sallallahu alayhi wa sallam) were bidding farewell to the living and the dead.
You used to go to visit the graves of the dead and supplicate for them.
Now, it was as if this was your final supplication for them.
It is also possible that you went to the field of Uhud and prayed at the graves of the martyrs of Uhud, and then, upon returning, delivered a sermon in the Prophet’s Mosque.
In this case, instead of supplication, this would be the funeral prayer (salat al-janazah).
This is the position of the Hanafis.
If the prayer was performed in the mosque, then it would be a funeral prayer in absentia (janazah gha’ibanah).
However, Allamah Anwar Kashmiri considers this to be a supplication (du‘a).

Inna ‘ardahu kama bayna Eylah ila Juhfah:
Regarding the length and width of the Pond of Kawthar (Hawd al-Kawthar), you (sallallahu alayhi wa sallam) described, at different times, the distance between various locations.
You mentioned the names of places according to the knowledge of those present.
The purpose was to convey its vastness and spaciousness.
Specifying or limiting the exact distance was not the objective.
Juhfah is a place near Rabigh, which is the miqat for the people of Sham (Greater Syria), and Eylah is a port located on the Red Sea (Bahr al-Qulzum), and it is about a month’s journey from Madinah.
