Commentary:
1:
That is, how much interval was there between the two.

2:
From this it is understood that the pre-dawn meal (suhoor) should be eaten at the very last time; this is the Sunnah method. However, it should be eaten before the true dawn (subh sadiq), and this interval should be equivalent to the time it takes to recite fifty verses.

Hadith Commentary:
(1)
The content of both these narrations is almost the same, that is, they mention the interval between the pre-dawn meal (suhoor) and the prayer, which is the amount of time it takes to recite fifty or sixty verses (ayat).
From this, it is understood that there was very little interval between suhoor and the prayer, and after finishing suhoor, they would soon stand for the prayer.
In view of these ahadith, Imam Bukhari rahimahullah holds the position that the Fajr prayer should be started in darkness after the true dawn (subh sadiq) appears.
This is explicitly stated in some ahadith, as narrated from Hazrat Abu Musa Ash'ari radi Allahu anhu that the Messenger of Allah sallallahu alayhi wa sallam would begin the morning prayer as soon as the true dawn appeared, to the extent that due to the darkness, the noble Companions radi Allahu anhum could not even recognize one another.
(Sahih Muslim, al-Masajid, Hadith: 1393(614))
It is narrated from Hazrat Ibn Abbas radi Allahu anhu that the Messenger of Allah sallallahu alayhi wa sallam said:
“There are two types of dawn (fajr):
One is the dawn in which eating becomes forbidden and prayer becomes permissible, and the other is the dawn in which prayer is forbidden but eating is permissible.”
(al-Mustadrak lil-Hakim: 191/1)
In the narration of Hazrat Jabir radi Allahu anhu, there is further clarification that the dawn which rises high like the tail of a wolf—in that, prayer is forbidden and eating is permissible; and the dawn which spreads along the horizons of the sky—in that, prayer is permissible and eating is forbidden.
(al-Mustadrak lil-Hakim: 191/1)
(2)
Hazrat Anas radi Allahu anhu did not participate in the pre-dawn meal (suhoor) with the Messenger of Allah sallallahu alayhi wa sallam.
In a detailed narration, it is mentioned that the Messenger of Allah sallallahu alayhi wa sallam said to Hazrat Anas radi Allahu anhu:
“I intend to fast, arrange some food, etc.”
So I brought dates and water and presented them to him. Then he said:
“Find a person who will join me in eating.”
So I brought Hazrat Zayd bin Thabit radi Allahu anhu, he came and participated in the suhoor. After finishing, the Prophet sallallahu alayhi wa sallam performed two units (rak‘ah) of prayer, then stood for the Fajr prayer.
(Fath al-Bari: 72/2)

Explanation:
Fifty or sixty verses can be recited within ten minutes. This hadith also proves that it is Sunnah to delay the pre-dawn meal (suhoor). Those who eat suhoor early in the night act contrary to the Sunnah.

Hadith Commentary:
Imam Bukhari rahimahullah wants to clarify here that from the ahadith mentioned previously, it is established that the Prophet sallallahu alayhi wa sallam, after performing the tahajjud prayer, would lie down, and then the mu’adhdhin would come to announce the time for the morning (fajr) prayer. However, it is also established from him that at that time he would not lie down, but rather would perform the morning prayer.

It was the practice of the Prophet sallallahu alayhi wa sallam in the month of Ramadan that after taking the pre-dawn meal (suhoor), he would pause briefly and then begin the fajr prayer while it was still dark (tafheem al-Bukhari).

Thus, it is understood that performing the fajr prayer during darkness (ghalas) is a sunnah. Those who deny this sunnah and always perform the fajr prayer close to sunrise are certainly acting contrary to the sunnah.

Hadith Commentary:
In this hadith, the routine of the Messenger of Allah (sallallahu alayhi wa sallam) during Ramadan is described: on ordinary days, he would remain asleep at the time of suhoor (pre-dawn meal), then rise and perform the morning (fajr) prayer. However, in Ramadan, after completing suhoor, he would engage in preparations for the morning prayer and then perform the prayer.

In some versions of Sahih al-Bukhari, this chapter heading appears in the following words:
"Whoever partook in suhoor, then prepared for prayer and did not sleep until he performed the morning prayer."
(‘Umdat al-Qari: 5/366)

Hadith Commentary:
In the chain of narration, the name of Qatadah ibn Di‘amah appears. His kunyah is Abu’l-Khattab al-Sadusi. He was blind and possessed a strong memory. Bakr ibn ‘Abdullah al-Muzani, a notable elder, says: “Whoever wishes to see the person with the strongest memory of his era should look at Qatadah.”
Qatadah himself says: “Whatever reaches my ears, my heart immediately preserves it.”
He narrates from ‘Abdullah ibn Sarjis, Anas (radi Allahu anhu), and many other individuals.
He passed away in 70 AH.
Rahimahullah (may Allah have mercy on him) (Ameen).

Hadith Commentary:
(1)
It is understood that one should delay the pre-dawn meal (suhoor).
It is against the Sunnah for a person to eat suhoor at midnight and then go to sleep.
The Sunnah is that one should finish suhoor a little before the break of dawn (fajr), and then engage in preparation for the Fajr prayer.
Hudhayfah radi Allahu anhu says:
We ate suhoor with the Messenger of Allah sallallahu alayhi wa sallam and continued eating until the day became bright, although the sun had not yet risen.
(Sunan an-Nasa’i, Kitab as-Siyam, Hadith: 2154)
This narration is contrary to the hadith of Zayd ibn Thabit radi Allahu anhu.
The scholars have given various answers to this.
The preferred view is that the narration of Hudhayfah is not authentically attributed (marfu‘an) to the Prophet, and therefore cannot be in opposition to authentic evidence.
And if it is accepted as authentic, then it would be considered abrogated (mansukh), and the narration of Zayd and other evidences on this subject would be its abrogators (nasikh).
(Dhakheerat al-‘Uqba Sharh Sunan an-Nasa’i: 350/20)
(2)
The Noble Qur’an has made fasting obligatory from the time the white thread becomes distinct, after which eating and drinking are forbidden, so how can suhoor be permissible after that? In short, the aforementioned hadith of Hudhayfah radi Allahu anhu is contrary to the Noble Qur’an. In addition, the hadith of Zayd radi Allahu anhu has been agreed upon by the two Shaykhs (al-Bukhari and Muslim).
It is mentioned in the hadith that eating and drinking are permitted until the adhan of Ibn Umm Maktum, so in short, a person should finish suhoor before the Fajr prayer.
(Fath al-Bari: 178/4)

Hadith Commentary:

Benefits and Issues:
➊ In Ramadan, there should be a considerable interval between the call to prayer (adhan) and the prayer (salah), and one should complete the pre-dawn meal (suhoor) before the adhan.

From this narration, it is understood that the questioner is Qatadah rahimahullah and the one responding is Anas radi Allahu anhu. Whereas from the first two narrations, it is understood that the questioner is Anas radi Allahu anhu and the one responding is Zayd ibn Thabit radi Allahu anhu. However, it is not unlikely that both are correct; that is, Anas radi Allahu anhu asked Zayd ibn Thabit radi Allahu anhu, and Qatadah rahimahullah, who was a student of Anas radi Allahu anhu, asked Anas radi Allahu anhu. There is no contradiction between the two incidents. And Allah knows best.

(1) Even to recite fifty verses with composure, at least ten minutes are necessary.

(2) Good manners should always remain before a person. The Companions (radi Allahu anhum) did not say, "We and the Messenger of Allah (sallallahu alayhi wa sallam) ate the pre-dawn meal (suhoor)," but rather said, "We ate the pre-dawn meal with the Messenger of Allah (sallallahu alayhi wa sallam)," because in this there is an indication towards following (his example).

Benefits and Issues:
➊ Although the pre-dawn meal (suhoor) can be eaten well before true dawn (subh sadiq), it is better to eat it in the last part of the night, shortly before true dawn.
➋ It is preferable to perform the Fajr prayer at its earliest time. The Messenger of Allah (sallallahu alayhi wa sallam) performed the Fajr prayer after a brief interval following the pre-dawn meal (suhoor).
