Bukhari

Hadith Commentary:
It was customary in Arabia that when the enemy drew near and someone spotted them, he would fear that the army might reach his people before he could. Therefore, he would strip naked and run quickly, shouting as he went.
Some say that he would take off his clothes, attach them to a stick like a flag, and run while shouting.

Hadith Commentary:
1.
The meaning of "uryaan" is: naked.
Among the Arabs, it was customary that when a person saw an enemy and wanted to warn his people about it, he would take off his clothes, wave them above his head, and shout loudly to inform his people, so that people from afar would realize that the situation was dangerous.
Some say that he would take off his clothes, attach them to a stick like a flag, and run while shouting.
The Messenger of Allah (sallallahu alayhi wa sallam) explained to his followers and those who disobeyed him through an example.
In reality, those who are obedient to you (sallallahu alayhi wa sallam) are the ones who follow and emulate your (sallallahu alayhi wa sallam) Sunnahs.
2.
Similarly, the Messenger of Allah (sallallahu alayhi wa sallam) has also warned people through another example: that my example is like the one who kindled a fire, so moths gathered around it and were ready to leap into the fire, while he tried to keep them away from the fire, but they overpowered him.
I am grabbing you by your waists, pulling you away from Hellfire, but you people are falling into it.
(Sahih al-Bukhari, al-Riqaq, Hadith: 6483)
In any case, the Messenger of Allah (sallallahu alayhi wa sallam) had such love and compassion for his Ummah that even a mother does not have such love and compassion for her suckling child.

Hadith Commentary:
This became a proverb in Arabia. What happened was that at some time, enemy armies invaded a country. One of the people of that country encountered these armies; they captured him and stripped off his clothes. In this state, naked and bare, he managed to escape and went to his countrymen to inform them: "Quickly make your preparations, the enemy has arrived." His countrymen believed him, since he was running naked and bare, and it was not his habit to go about unclothed.

The relevance to the chapter is as follows: The Messenger of Allah (sallallahu alayhi wa sallam) warned them against sins and disobedience to Allah, and informed them that Allah's punishment is prepared for the sinners. Therefore, repent from sins and protect yourselves. Whoever accepted his words, embraced Islam, repented from shirk, disbelief, and sin, was saved. But whoever did not accept, as soon as morning came—that is, as soon as he died—he was destroyed and seized by the punishment of Allah.

Hadith Commentary:
(1)
Among the Arabs, it was customary that a person who warned people of an enemy would remove his clothes and become naked, and would whirl the clothes over his head, then announce that the enemy was about to attack.

(2)
The meaning of the hadith is that I am clearly warning you; be concerned about saving yourselves from Hellfire. The explanation of this hadith is found in another narration: Hazrat Buraidah radi Allahu anhu says that the Messenger of Allah sallallahu alayhi wa sallam once went out and called out three times, saying:
“My example and yours is like a people who feared that an enemy might suddenly attack them. They sent a man to keep watch. One day, he saw that the enemy was preparing to attack them, so he immediately ran from there to inform his people of the enemy’s preparations, lest the enemy attack and destroy them. Thus, he removed his clothes, ran from there, and began to announce: O people! Take heed for yourselves, make arrangements to save yourselves.”
(Musnad Ahmad: 248/5)

(3)
In any case, those who heed the warning of the Messenger of Allah sallallahu alayhi wa sallam and refrain from sins will be saved from Hellfire, while those who do not refrain from sins will become fuel for Hellfire.
Wa Allahu al-musta‘an.

Hadith Commentary:
Vocabulary of the Hadith:
(1)
Al-nadheer al-‘uryan:
A warner who warns while naked and unclothed.
In the era of Jahiliyyah (pre-Islamic ignorance), it was a custom and tradition that if a person wanted to alert his people from afar about some danger, he would remove his clothes and signal with those clothes that there was danger and that they should prepare themselves. This was considered proof of his truthfulness. Since the statement of a Messenger is definitive and certain, in which there is no possibility of falsehood, he has been likened to al-nadheer al-‘uryan.

(2)
Al-najaa’:
That is, “Iṭlubū al-najaa’” (seek salvation):
Adopt the way of salvation and deliverance,
seek your path to salvation.

(3)
Adlajū:
They set out at dusk,
and continued slowly throughout the night.
‘Ala mahlihim or mahlatihim:
They kept moving and escaped the reach of the enemy.

(4)
Ṣabbahahum al-jaysh:
The army attacked them early in the morning while they were asleep.
The meaning is that the enemy attacked suddenly and did not give them a chance to confront or prepare.

(5)
Fajtāḥahum:
He uprooted them from their very foundation,
that is, he utterly destroyed them,
none of them survived.

Benefits and Issues:
The Messenger, like the vanguard or the guardian and protector of the people, possesses a passion for the salvation of his Ummah and for protecting them from dangers, and he informs them of all those matters that could be a cause of harm or destruction for them. Therefore, the Ummah can only remain safe from dangers and losses if it adheres to the guidance and teachings of its Messenger; otherwise, it cannot escape ruin and destruction. Nowadays, we are witnessing this reality with our own eyes, but the faculty of taking heed and learning lessons has been distorted, and thus we do not awaken from the slumber of heedlessness.

Jurisprudence of the Hadith:
➊ Obedience to the Messenger of Allah (sallallahu alayhi wa sallam) is obligatory.
➋ The solitary report (khabar wahid) narrated by a truthful narrator is authoritative evidence.
➌ It is permissible to present examples for the propagation of religion, provided that such examples do not contradict any religious ruling.
➍ Those who do not act upon the Qur’an and Hadith will be ruined and destroyed in the heavenly court and the Hereafter, and (by the command of Allah) will remain in punishment.
