Bukhari

Hadith Commentary:
It is understood from this that it is permissible to enter the mosque while armed; however, if there is any sharp-edged object, one should cover its edge with the hand so that no one else is injured.
As mentioned in one narration, the aforementioned man passed through the mosque with arrows whose tips were exposed, so he was instructed to hold them by their heads so that no Muslim would be harmed by them.
In another narration from Sahih Muslim, it is stated that the man came to the mosque after making arrows in order to give them in charity to the mujahideen so that they could be used in jihad.
(Sahih Muslim, Al-Birr wa al-Silah, Hadith: 6663 (2614))

Hadith Footnote:
Vocabulary of the Hadith:
Nasl, nasool:
The tip of an arrow or spear,
Blade,
Pointed iron.

719. Commentary: In the detailed narration, it is mentioned that he had exposed the arrows from the pointed ends. There was a danger that they might strike someone, so the Prophet (sallallahu alayhi wa sallam) said: "Hold the arrows by their pointed ends so that they do not cause harm." Thus, it is permissible to bring weapons into the mosque, but in a secured state so that they do not accidentally strike anyone. Although, it is better to avoid bringing weapons altogether, because if tempers flare in the presence of weapons, they might be used, which could result in great turmoil.

Benefits and Issues:
➊
If a person has any pointed object, he should exercise caution while passing by others so that, unintentionally, it does not injure anyone.

➋
By "nisal" (pikan) is meant the pointed tip of an arrow, which is made of iron and, when it strikes the prey, wounds it.

➌
The sharp tip of a knife, scissors, etc., can also prick someone. If goods loaded on a donkey cart, ox cart, or truck are of such a nature that there is a risk of harming a passerby, then it is necessary to take all required precautionary measures.

➍
A rifle, gun, or Kalashnikov, etc., should not be kept loaded, nor should one take them in such a state to the market, mosque, or any place where people gather, so that an accidental incident does not occur.

➎
At the end of the hadith, there is this phrase:
(qala na‘am)
Some scholars, while translating, have considered it to be the statement of the Companion and have translated it as:
"He said: Very good," or "He said: Excellent."
In reality, this is the statement of ‘Amr ibn Dinar rahimahullah, that when his student Sufyan ibn ‘Uyaynah rahimahullah asked him:
"Did you hear this hadith from Jabir radi Allahu anhu?" ‘Amr ibn Dinar replied:
"Yes (I heard it)."
This is one of the methods of hadith transmission, where the student recites the hadith and the teacher confirms that the hadith is as stated.
In the terminology of the hadith scholars (muhaddithin), this is called "‘ard."

Benefit:
From this hadith, it is understood that a sword or spear should be held from its tip, so that no harm comes to anyone. It should be remembered that when holding a gun or pistol, the finger should not be placed on the trigger, lest the gun accidentally discharge. A person who is walking with an exposed weapon should be instructed to handle it with care.
