Bukhari

Appropriateness between the Chapter and the Hadith:

This was the sermon (khutbah) of the Day of ‘Arafah, and the sermon of Mina is the later one which was delivered on the tenth day, in which the clarification of the Day of Sacrifice (Yawm al-Nahr) is explicitly present.

Hafiz Ibn Hajar rahimahullah says:

«فہذا الحدیث الذى وقع فى الصحیح أنہ صلى اللہ علیہ وسلم خطب بہ یوم النحر وقد ثبت انہ خطب بہ قبل ذالک یوم عرفہ»

That is, “It is explicitly mentioned in the hadith of Sahih al-Bukhari that the Prophet sallallahu alayhi wa sallam delivered a sermon on the Day of Sacrifice (Yawm al-Nahr), and it is also established that before this, the Prophet sallallahu alayhi wa sallam delivered a sermon on the Day of ‘Arafah as well.”

In Hashiyat al-Sindi, two answers have been given regarding the appropriateness between the chapter heading (tarjamat al-bab) and the hadith. Imam al-Sindi writes:

«بأن یقال أیام من یشملہ أیضًا تغلیبًا، أو باعتبار أن ابتداء یوم عرفۃ یکون بمنی۔» [حاشیۃ السندى، ج 1، ص : 299]

From this clarification of Imam al-Sindi, it becomes evident that the beginning of the Day of ‘Arafah is from Mina; when the Prophet sallallahu alayhi wa sallam delivered the sermon at Mina, then necessarily he would have delivered the sermon at ‘Arafah as well. Therefore, from here the appropriateness between the chapter and the hadith becomes apparent.

Thus, when the Prophet sallallahu alayhi wa sallam delivered both sermons, the sermon at Mina is also established, which is a very important sermon.

Both are referred to as sermons (khutbah) because the benefit of both sermons is independently established.

Imam Qastallani rahimahullah says:

«بأن البخاری أراد أن یبین أن الراوی قد سماہا : ”خطبۃ“ کما سمى التى وقعت فى عرفات خطبۃ۔» [إرشاد الساری، ج 3، ص : 485]

“The purpose of Imam al-Bukhari rahimahullah is that (the day of Mina) was named as a sermon, just as the narrator referred to the sermon (of the day of ‘Arafah) by the name of sermon.”

Therefore, both were indeed sermons; the beginning of the Day of ‘Arafah was from Mina, while the sermon at ‘Arafah was also extremely important. Thus, from here the appropriateness between the chapter heading and the hadith will be established.

Hadith Commentary:
Delivering this sermon on the Day of Sacrifice (Yawm al-Nahr) is a Sunnah. In it, the rulings regarding stoning (rami) and other related matters should be explained. This is the third of the four sermons of Hajj, and all are after the Eid prayer except for the sermon of ‘Arafah, which is before the prayer. On that day, two sermons should be delivered.
Qastallani (Wahidi)
The great objective of Hajj is to invite the world of Islam to God-consciousness and mutual unity, and the best opportunity for this is precisely these sermons. Therefore, it is the duty of the preacher that, along with the rulings of Hajj, he should also shed light on the issues facing the Muslim world and invite the Muslims to God-consciousness, adherence to the Book and Sunnah, and mutual unity, for this is the greatest purpose of Hajj.
In this sermon, the Messenger of Allah (sallallahu alayhi wa sallam) raised his head towards the sky to call upon Allah. From this, the attribute of elevation (direction of above) and Allah’s rising over the Throne (istawa ‘ala al-‘arsh) are affirmed for Allah Most High (bi-la kayf).
The tenth of Dhu al-Hijjah is called Yawm al-Nahr (Day of Sacrifice); the eighth is Yawm al-Tarwiyah; the ninth is Yawm ‘Arafah; the eleventh is Yawm al-Qarr; the twelfth is Yawm al-Nafr al-Awwal; and the thirteenth is Yawm al-Nafr al-Thani.
And the tenth, eleventh, twelfth, and thirteenth are called the Days of Tashriq (Ayyam al-Tashriq).
