Hadith Footnote:
Vocabulary of the Hadith:
Janan:
Plural of "jaan" (serpent),
A white and slender or thin snake.

Hadith Commentary:
Imam al-Bukhari rahimahullah previously established a chapter under the noble verse: ﴿وَبَثَّ فِيهَا مِنْ كُلِّ دَابَّةٍ ﴾ (al-Baqarah: 164).
All of these ahadith are related to that same chapter.
In between, the mention of the goat (bakri) came up incidentally.
Due to its importance, he deemed it appropriate to establish a separate chapter for it.
Then, after the ahadith regarding the goat, under the chapter pertaining to the verse ﴿وَبَثَّ فِيهَا مِنْ كُلِّ دَابَّةٍ ﴾ (al-Baqarah: 164),
he brought all those ahadith in which various types of animals are mentioned.
So reflect, and may Allah grant you success.

Hadith Commentary:
➊
In these narrations, various types of snakes are mentioned; this is why Imam Bukhari rahimahullah has narrated them.
➋
The meaning of "silkh" is the slough (shedding) that a snake casts off.
It is like soft paper.
"Al-jaan" refers to those snakes that live in houses and are white in color.
We have already mentioned the details regarding them earlier.
➌
From the previous ahadith, it is understood that there are two types of snakes: those with two stripes and those with cut tails, whereas from Hadith 3310, it appears that this is one and the same type, because there is no conjunction (harf atf) between them.
According to our inclination, regarding snakes, these two characteristics are sometimes found together in a single snake and sometimes found separately in two different snakes.
The command of the Messenger of Allah sallallahu alayhi wa sallam applies to both types.
And sometimes the conjunction "waaw" (and) combines two characteristics as well; on this basis, the meaning of the hadith is: kill that snake which is both cut-tailed and two-striped.
And Allah knows best.
