Bukhari

Hadith Commentary:
That is, if food is presented, one should eat first so that the prayer can then be performed with tranquility.

These ahadith require that when both food and prayer are present, one should eat first so that the heart does not remain attached to the food and the prayer may be performed with tranquility and composure. Similarly, if the prayer is established while one is eating, one should not leave the food, but rather, after finishing, proceed to the prayer with peace of mind, as the Messenger of Allah (sallallahu alayhi wa sallam) said:
“When any of you is having food, he should not hasten until he fulfills his need from it, even if the iqamah for prayer has been pronounced.” (Sahih al-Bukhari, al-Adhan, Hadith: 674)

This principle applies to all prayers. Since food is usually eaten at the time of Maghrib or Isha prayer, these are the ones mentioned in the ahadith.

Imam Bukhari rahimahullah has narrated this report with two different wordings:
In one narration, it is "idha hadara," which means: when it is present and ready.
In another narration, it is "idha wudi‘a," meaning "when it is presented."
Since the wording "hadara" is more general, it will be understood in the sense of "wudi‘a."
This is also supported by other narrations whose wordings are "idha quddima" or "idha quriba."
In a narration of Sahih Muslim, it is stated that when food is present or one is compelled by the need to relieve oneself, then in such circumstances, prayer is not to be performed.
(Sahih Muslim, al-Masajid, Hadith: 1246(560)
and Fath al-Bari: 280/2)

Regarding giving precedence to food over prayer, scholars and jurists have presented various explanations:
Some scholars say that if there is a fear that the food will spoil, then there is no harm in doing so.
Some hold the view that this applies in the case of scarcity of food, that is, when the food is little and the eaters are many, and there is a fear that if the prayer is started, the food will be finished; in such circumstances, one should eat first and then perform the prayer.
In our view, the better explanation is that the aforementioned permission is in the case where there is a fear of preoccupation of the heart, i.e., if one does not eat, the mind will remain occupied with the thought of food during the prayer.
If such is the case, then one should eat first and then perform the prayer.
Imam Bukhari rahimahullah also seems inclined towards this, because this is explicitly stated in the saying of Abu Darda’ radi Allahu anhu.
Imam Bukhari rahimahullah’s inclination is also evident from the traditions given under the chapter heading.
(Fath al-Bari: 20/2)
And Allah knows best.

Benefit:
The instruction to eat food before the prayer applies only in the case of severe hunger.
Otherwise, avoiding congregational prayer is highly inappropriate.
And Allah knows best.

Benefit:
If food is present and the call to commence prayer (iqamah) is given, then one should eat first, so that the humility and concentration (khushu‘ and khudu‘) in prayer are not affected, and the prayer is performed with complete attentiveness. This rule applies to all prayers. Since food is usually eaten at the time of Maghrib or ‘Isha, these are the prayers mentioned in the ahadith. The imam is an exception to this, because he has to lead the prayer. See: (Sahih al-Bukhari: 675, al-Adhan, “The Imam going to prayer while something to eat is in his hand”).
