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

AsSalamu Alaikum Wa Rahmatullahi Wa Barakatuhu!

Rasulullah Sallallahu Alaihi Wa Sallam sent a Sariyyia (an expedition) to a tribe, the Mujahidun found a few people in prostration (to protect themselves) but they were killed.
When Rasulullah Sallillahu Alaihi Wa Sallam was informed of the incident, he said,

أَنَا بَرِيءٌ مِنْ كُلِّ مُسْلِمٍ يُقِيمُ بَيْنَ أَظْهُرِ الْمُشْرِكِينَ.

“I disown every Muslim who settles among the Mushrikeen”.

(Sunan Abu Dawud 2645. Saheeh).

My brother, You know that the entire Kuffar world is fighting against Islam, right?
Imagine, the way Kuffar has been bombing the Muslims in the Middle East, the same way Muslim countries are bombing the Kuffar’s lands. Would you then live among the Kuffar, in the Kuffar’s Land?

And if someone happens to live among the Kuffar at the time of war and therefore dies from those attacks, what would be his status with Allah, Al Haseeb, The Reckoner?
Can he show an excuse to the angels, “I was in the ‘No Fighting Zone’ Sir!”

Usually, when two countries fight and bombard each other, would you find any regular nationals living among the enemies, in the enemy country?

No way! Both countries warn their respective citizens to evacuate long before they engage in the bombing (For example, the ongoing Israel-Filistine war and Russia-Ukraine war)

To give you a practical example, imagine, the way Kuffar bombarded Iraq, the same way Iraq’s missiles and jet fighters bombarded America. Tell me, which American will go to live in Iraq or which Iraqi Muslim will go to live in America? You won’t find any.
Check the history, when the confederation of the Kuffar was fighting a crusade against Muslims, did any Muslim live and settle among the Kuffar, in the Kuffar’s lands, under the Kuffar’s authority?

and then, what about giving you the most recent example?
Filistine and Israel are at war right now. You tell me, would any Filistine would go and live in Israel?
It’s absurd, isn’t it?

Then, why are you living in the Kuffar’s lands now?
Is it because there’s no harm, no bombing attack coming from the Muslim countries to the Kuffar’s lands, right?
Therefore, you feel safe, right!
Or are you in the delusion that Kuffar is actually not fighting Islam, they are fighting the ‘terrorists’, they are fighting to defuse the ‘Weapon of Mass Destruction’!

And I hope that you are not in that delusion.
The kuffar and their entire confederations are fighting the Muslims and fighting against Islam. This is the truth. If you really know this truth, then, you really won’t want to live among the Kuffar, in the Kuffar’s land, under the Kuffar’s authority if there is a fighting back from the Muslim countries with the Kuffar’s countries.

So, my brother, Is this the fact that because the Kuffar’s lands are not attacked by the Muslim countries makes it permissible/ safe for you to live in the Kuffar’s lands?
But what if a Muslim country starts an attack while you’re among the Kuffar, therefore, you’re subjected to that attack?
In what status will you die then?
What will be your status with Allah Subhanahu Wa Ta’ala according to the Hadith quoted above?

So, my brother, can you understand your status now?

Think of this, Muslims who were in prostration were killed but Rasulullah Sallillahu Alaihi Wa Sallam didn’t rebuke the Mujahideen for killing the Muslims, nor did He criticize them saying, “It is haram in Islam to kill innocent people” though it is true that it is Haram in Islam to kill innocent people (Quran 5:32).

He neither punished them nor make a Takfir on them saying “Killing a Muslim is Kufr” though it is true that it is Kufr to kill a Muslim (except in certain events). (Quran 4:93) (Saheeh Bukhari 6785, 6865)

And then, read this Ayah now.
This Ayah was revealed about those Muslims who didn’t make Hijrah to Madinah and then, they were killed in Badr.

“Verily, as for those whom the angels take (in death) while they are wronging themselves (as they stayed among the disbelievers even though emigration was obligatory for them), they (angels) say (to them):

“In what (condition) were you?”
They reply: “We were weak and oppressed on the earth.”
They (angels) say: “Was not the earth of Allah spacious enough for you to emigrate therein?”
Such men will find their abode in Hell — what an evil destination!”
[al-Nisa’ 4:97]

May Allah save us from being killed while living in the Kuffar’s land.
May Allah save us from dying in the Kuffar’s lands.
May Allah make our Hijrah easy!
Ameen.
Wa Allahu A’alam.

And here is the full Hadith.

بَابُ النَّهْيِ عَنْ قَتْلِ مَنِ اعْتَصَمَ بِالسُّجُودِ حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ إِسْمَاعِيلَ، عَنْ قَيْسٍ، عَنْ جَرِيرِ بْنِ عَبْدِ اللَّهِ، قَالَ: بَعَثَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ سَرِيَّةً إِلَى خَثْعَمٍ فَاعْتَصَمَ نَاسٌ مِنْهُمْ بِالسُّجُودِ، فَأَسْرَعَ فِيهِمُ الْقَتْلَ قَالَ: فَبَلَغَ ذَلِكَ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ فَأَمَرَ لَهُمْ بِنِصْفِ الْعَقْلِ وَقَالَ: أَنَا بَرِيءٌ مِنْ كُلِّ مُسْلِمٍ يُقِيمُ بَيْنَ أَظْهُرِ الْمُشْرِكِينَ. قَالُوا: يَا رَسُولَ اللَّهِ لِمَ؟ قَالَ: لَا تَرَاءَى نَارَاهُمَا قَالَ أَبُو دَاوُدَ: رَوَاهُ هُشَيْمٌ، وَمَعْمَرٌ، وَخَالِدٌ الْوَاسِطِيُّ، وَجَمَاعَةٌ لَمْ يَذْكُرُوا جَرِيرًا صحيح دون جملة العقل
