Bismillah!
Al Hamdulillah!
Wa AsSalatu AsSalamu A’ala Rasulillah!

How important is the matter of not living with the Mushrikeen?
How important are the words of a person what he speaks as the last advice before his death?
These are such important words that even these words get a legal status, in case, you don’t know it.

Then, what about the instructions of Rasulullah Sallallahu Alaihi Wa Sallam on his deathbed?
How important that could be for the Ummah?
For sure, It is the most important legal binding on the Ummah, the most important Shariah of Rasulullah Sallallahu Alaihi Wa Sallam.

So, what was the last message of Rasulullah at the last moments of his death?
“Expel out the Mushrikeen from the territory of Arabia.”

Subhanallah!
Why did this matter become such important to Rasulullah?
It’s because He was concerned about his Ummah so much that he wanted to give a final prescription, and the final Shariah for his Ummah to stay on the right path!

So, he prescribed, “Do three things so that you won’t go astray”
And the first instruction was this:
“Expel out the Mushrikeen from the territory of Arabia.”

What’s the meaning of it?
It means, he did not want his Ummah to be among the Mushrikeen or
he did not want the Mushrikeen around the Muslims.
Because he knew that living around the Mushrikeen would lead them to go astray, lead them to engage in Shirk, the greatest sin of all.

And what do you see today?
How many Muslims and Muslim kids take part in one way or another in the pagan rituals of Halloween, Santa, and Christmas rituals?
How many Muslim youths in Bangladesh, Pakistan, Malaysia, and Indonesia take part in Hindu pagan rituals?
And soon the Muslims of the Arabian peninsula would engage or take part in these rituals as the present authorities of the kingdoms allowing the Mushrikeen to build their worship places in the lands of Islam.

So, no wonder, why won’t you see the Muslims gone astray today?
They are not only living among the Mushrikeen rather they are living under the authority of the Mushrikeen! (In the Kuffar’s land and then, whomever it applies to)
Thus we are witnessing the consequences that Rasulullah Sallillahu Alaihi Wa Sallam warned about.

Let’s site a few of such scenarios here:

Scenario 1:
This author himself witnessed a business house owned and run by Muslims, decorated with Christmas decorations during this festival of Shirk.

Scenario 2:
An 11-year-old girl asks her parents to put a Christmas tree in the house: And the Jaheel parents ask Fatwa about it:

That’s how it is so important to move away from living under the authority of the Mushrikeen and from moving away from living among the Mushikeen. Saving yourself and your generations from Shirk.

And Allah knows best.
May Allah protect us from going astray.
May Allah save us from living among the Mushrikeen.
May Allah make our Hijrah easy.
Ameen.

Here is the full text of the Hadith:
Saheeh Muslim 4124 (20/1637)

Sa’id b. Jubair reported that Ibn ‘Abbas said:
Thursday, (and then said): What is this Thursday?
He then wept so much that his tears moistened the pebbles.
I said: Ibn ‘Abbas, what is (significant) about Thursday?

He (Ibn ‘Abbas) said:
The illness of Rasulullah Sallallahu Alaihi Wa Sallam took a serious turn (on this day),
and he said:

“Come to me, so that I should write for you a document that you may not go astray after me.”
They (the Companions around him) disputed, and it is not meet to dispute in the presence of Rasulullah.
They said:
How is (Rasulillah)?
Has he lost his consciousness? Try to learn from him (this point).

He (Rasulillah) said:
“Leave me. I am better in the state (than the one in which you are engaged).
I make a will about three things:
Turn out the polytheists from the territory of Arabia;
show hospitality to the (foreign) delegations as I used to show them hospitality.”

He (the narrator) said: He (Ibn Abbas) kept silent on the third point,
or he (the narrator) said:
But I forgot that.

This hadith was mentioned through another chain.

—
Also in Saheeh Bukhari 3053 stated:
Rasulullah on his death-bed, gave three orders saying,
“Expel the pagans from the Arabian Peninsula”

Also in Saheeh Bukhari 4486 stated:
It has been narrated by ‘Umar bin. al-Khattib that he heard Rasulullah Sallallahu Alaihi Wa Sallam said,
“I will expel the Jews and Christians from the Arabian Peninsula and will not leave any but Muslim.”

Please note:
There is another hadith (Saheeh Muslim 4126) narrated from a different chain that doesn’t say Rasulullah Sallallahu Alahi Wa Sallam was able to write because of interference from Umar Radiallahu Anhu.

But how do we reconcile these Hadiths?
By the intention of Rasulullah and later the actions of the Sahaba.
We know from history that no Mushrikeen were allowed to live in the Arabian peninsula.
Therefore, the implementation of the Hadiths itself proves the authenticity of these Hadiths mentioned above.
And Allah knows best.
