What is obligatory for me if a snake enters my house?

The questioner : I went to the house, O our Shaykh, and I found it, and it was said to me that there is a snake that entered the hole.

The Shaykh: Yes

The questioner : So there were two, meaning one was killed and the second entered the hole.

The Shaykh : Yes.

The questioner : What should I do, O our Shaykh?

The Shaykh : This is the first time you have seen it.
The student : Yes, it is the first time we have seen it in the house.

The Shaykh : In the house.
The student : Yes.

The Shaykh : Here, it is necessary to warn it, and killing the first one was a mistake.
The student : My wife did not know, O Shaykh.

The Shaykh : I know, but we are discussing the reality of the situation now.
The student : Yes.

The Shaykh : That is, we are not speaking now about legal accountability to say whether she knew or did not know, but rather we are speaking now about what can be expressed to protect the house and those in it from the harms of the jinn, who sometimes take the form of snakes.
The student : Yes, O our Shaykh.

The Shaykh : Perhaps you understood the difference.
The student : Yes, yes. May Allah reward you with good and bless you.

The Shaykh : May Allah preserve you. So the point now is that I said killing the first snake was a mistake.
The student : Without the slightest doubt.

The Shaykh : Ah, now, so that the mistake is not repeated, you warn the snake that is present, and it may have offspring that you have not seen, and those offspring may be in the hole. So it is warned with the warning of Sulayman (peace and blessings be upon him).
The student : (Peace and blessings be upon him).

The Shaykh : It is said to it that if it is a jinn, it will hear and understand, and if it is a harmful animal, it will not hear, or at least it will hear but not understand because it is an animal. So in the first case, if it is a jinn that heard and understood and was warned, it knows that by the covenant of Sulayman (peace and blessings be upon him), it is obligatory for it to come out of its hole in this house inhabited by humans. If it does not do so, it is killed, and there is no harm on the one who kills it in this case.
The student : May Allah reward you with good and bless you.

The Shaykh : But if it is an animal, it is killed, and it is left where it has cast its burden, as the mother of the "qash'um" is said to be.
The student : May Allah reward you with good.

The Shaykh : The answer is clear.
The student : Yes, O our Shaykh. What is the appropriate formula to warn it? What do I say to it?

The Shaykh : There is nothing specific that has been transmitted here, but the two words that convey the meaning are: "I warn you by the covenant of Sulayman (peace and blessings be upon him) to come out of the house."
The student : Yes.

The Shaykh : And that is all.
The student : May Allah reward you with good and bless you, O our Shaykh.

The Shaykh : And this is repeated three times.
The student : Yes, O our Shaykh.

The Shaykh : It is repeated three times, meaning if it comes out again, you warn it a second time, and so on for the third time. If it is warned three times and comes out, it is killed; otherwise, before that, it is not.
The student : Yes, yes. Meaning, after the three times, if it comes out of the hole, O Shaykh?

The Shaykh : Yes, you kill it.
The student : Yes, yes. May Allah bless you, O our Shaykh.

The Shaykh : Our brother al-Khatib is with you.
Another student: Brother Abu Yusuf.
The student : Yes, O Shaykh. May Allah reward you with good and bless you, O Shaykh.

The Shaykh : May Allah preserve you.
