Bukhari

Hadith Commentary:
From this hadith, Imam Bukhari rahimahullah has deduced that the congregational prayer (jama‘ah) of ‘Isha and Fajr holds greater virtue than the congregational prayer of the other prayers, and that the Shari‘ah places great emphasis on these two prayers.
It is for this reason that the Prophet sallallahu alayhi wa sallam intended to burn those who did not participate in them.
This is the very objective of the chapter, and the correspondence between the chapter heading and the hadith is evident.

Hadith Commentary:
(1)
Reflecting on the hadith reveals that those whose houses the Messenger of Allah (sallallahu alayhi wa sallam) intended to burn were not hypocrites (munafiqun), but rather belonged to the people of Islam. They were merely warned due to their laziness, and their behavior was described as hypocritical, cautioning them against a bad end. In general, all prayers are burdensome for the hypocrites, as Allah the Exalted has stated that the hypocrites come to prayer with heaviness and laziness (). (At-Tawbah 9:54) However, the ‘Isha and Fajr prayers are especially burdensome, because at the time of ‘Isha, due to the fatigue of daily work, one desires rest and comfort, and in the morning, due to sleep, the temperament becomes heavy. Among the hypocrites, the spirit of sacrifice is absent, which is why these two prayers are particularly difficult for them.

(2)
The Messenger of Allah (sallallahu alayhi wa sallam) did not put his intention into action; rather, as is known from other ahadith, he abandoned the idea out of consideration for their women and children.

Commentary:
(1)
Preferring physical comfort and ease over acts of righteousness is a sign of weak faith. A believer performs good deeds for the pleasure of Allah; due to the hope of reward, even difficult acts of righteousness become easy for him. A hypocrite, being deprived of faith, does not seek the reward of the Hereafter; he is compelled to perform the prayer so that he may be considered a Muslim, thus acts of righteousness feel burdensome to him like forced labor. Since the ‘Isha and Fajr prayers involve physical hardship and require striving against the self (nafs), the hypocrite finds them especially difficult.

(2)
A person who performs these prayers regularly and with eagerness practically proves that he is free from hypocrisy.

(3)
The act of worship that is more burdensome upon the self carries greater reward, provided it is not contrary to the Sunnah.

Takhrij:
«أخرجه البخاري، الأذان، باب فضل العشاء في الجماعة، حديث:657، ومسلم، المساجد، باب فضل صلاة الجماعة، حديث:651.»©Explanation:
These prayers have been described as extremely burdensome and heavy.
‘Isha is considered burdensome because, at that time, tired and exhausted people try to go to sleep, or they perform the prayer alone and then go to sleep, giving no special importance to the congregation. Fajr is burdensome because the shaytan does not let people, who are overcome by sleep, get up at all.
