We live in an area that is pretty secluded and as such, it is frequented by many dangerous and venomous snakes.
Were a family of 14 (8 Adults and 6 Kids) and I fear for their safety. We’ve so far called Wildlife Rescue units every time we have spotted snakes, but they only oblige if the snake is in the vicinity of a home. They refuse to come if the snake is found outdoors/open areas. My questions are the following:

1. Can I kill these snakes for the only reason of Safety of family members?

2. I know that Jinns take the form of snakes, so what is the ruling on killing them?

3. Is it true that killing a snake that is a Jinn brings bad luck?

Please also note that we have spent enough money on cleaning and leveling adjacent vacant lands and spraying chemicals to keep snakes and rodents away, but nothing has helped so far. Please answer at your earliest convenience. May Allaah (Subhaana Wa Ta A’la) bless you for the great job you are doing. May you be blessed and rewarded for every letter that is thought of and typed.

The Messenger (blessings and peace of Allah be upon him)
enjoined the killing of snakes, and this is general in meaning and applies
to all kinds of snakes, in any place. But if the snake is inside the house,
it should not be killed until it has been warned three times; that is
because of the possibility that it may be a jinn. Then if it appears after
that, it may be killed.

It was narrated from Ibn ‘Umar (may Allah be pleased with
him) that he heard the Messenger of Allah (blessings and peace of Allah be
upon him) address the people from the minbar, saying: “Kill snakes.”

‘Abdullah ibn ‘Umar said: After that, I would not leave any
snake that I saw but I would kill it.

Narrated by al-Bukhaari (3299) and Muslim (3233)

Abu Dawood (5249) narrated that Ibn Mas‘ood said: The
Messenger of Allah (blessings and peace of Allah be upon him) said: “Kill
all the snakes, and whoever fears their revenge does not belong to me.”

Classed as saheeh by al-Albaani in Saheeh Abi Dawood

Muslim (2233) narrated that Naafi‘ said: One day ‘Abdullah
ibn ‘Umar was was at a ruin of his, when he saw the flash of a small snake.
He said: Find this snake and kill it. Abu Lubaabah al-Ansaari said: I heard
the Messenger of Allah (blessings and peace of Allah be upon him) forbid
killing the small snakes that live in houses, except the short-tailed snake
and the one with two stripes, for they are the ones that cause blindness and
miscarriages.

And Muslim (2236) narrated that Abu’s-Saa’ib said: We entered
upon Abu Sa‘eed al-Khudri, and whilst we were sitting there, we heard a
movement beneath the bed. We looked and saw a snake… and he quoted the
hadith, in which it says: The Messenger of Allah (blessings and peace of
Allah be upon him) said: “These houses have inhabitants. If you see any of
them, ask them to leave for three days. If it goes (all well and good),
otherwise kill it, for it is a kaafir.”

Ibn ‘Abd al-Barr (may Allah have mercy on him) said:

Some scholars said: It is not essential for snakes to be
warned or urged or asked to leave except in Madinah only. Others said that
Madinah and other places are the same in that regard, because some snakes
are jinn and may be found in Madinah and elsewhere, and whoever among them
Allah wills may be Muslim. Maalik said: What I prefer is that the snakes
that are found in houses, in Madinah and elsewhere, should be warned for
three days, but snakes should not be warned if they are found in the desert.

Ibn ‘Abd al-Barr said:

It is preferable that all snakes that are found in houses
should be warned, as Maalik said. What is meant by warning is that the
person who sees a snake in his house should say: I urge you, O snake, not to
appear before us or harm us. End quote.

(16/263)

Ibn ‘Abd al-Barr (may Allah have mercy on him) said:

The scholars are unanimously agreed that it is permissible to
kill desert snakes, whether they are small or large, no matter what type
they are. End quote.


At-Tamheed

(16/28)

So there is nothing wrong with you killing snakes that are
outside the house. As for those that are found inside the house, they should
not be killed until they have been warned for three days.

With regard to the view that killing the jinn that appear in
the form of snakes brings bad luck, this is a false view for which there is
no basis.

And Allah knows best.
