Not true. They teach you wrong Koran in Sweden.
We are reading the one without the Gannet...
"This was the reason for Islam's view on at-ta'arrub ba'd al-hijra as reflected in many ahadith. At-ta'arrub ba'd al-hijra literally means "becoming shorn of one's percepts of faith after migrating [to city]," and technically, it means leaving an environment where you could follow Islam and moving to a place where you maybe prone to not following Islam. Such a migration is counted as one of the major sins."
"This is a very complex issue.. however the key point that is being missed in all these postings that are being brought up is that living in NON Muslim lands is in relation to a land that is not in conflict or not attacking/slaughtering Muslims/Muslim Lands.. THIS iSSUE IS MORE OF LIVING AMONGST A PEOPLE WHO ARE ATTACKING MUSLIMS/MUSLIM LANDS
So whether you're living in the US/UK you're not living in a 'non-muslim' land only... you're living in a land that is at war and killing Muslims.
What is the scholarly consensus on living amongst those who are killing Muslims? We can go to the Quraysh on this one and what the Prophet SAWS said regarding those who live amongst them -- ' they strenghten their numbers '.
Al-Hassan Ibn Salih said: "whoever remains in the land of the enemy, will be treated like the disbelievers, so long as he was able to join the Muslims but did not do it. If one of the disbelievers accepts Islam, but still remains with the disbelievers, even though he was able to go to join the Muslims, he is to be treated like them; neither his blood nor his property will be protected.
Al-Hassan said: "If a Muslim emigrates to the land of the disbelievers, yet does not renounce Islam, he will be an apostate by virtue of his abandonment of 'Dar ul-Islam"' . (The Arabic text of the preceding passage refers to the land of the disbelievers as ‘dar ul-harb' and 'Ard ul-Adu', that is: the 'land of the enemy'; this indicates an active military opposition to the Muslims, as if in a state of war).
Sheikh Qahtani says: But those who would emigrate to non-Muslim lands in search of wealth or prosperity to live under their protection, while they were able to go to live amongst the Muslims in their own land, but still do not withdraw themselves from the disbelievers; such people are not far from the fold of disbelief, and we can find no possible excuse for them, so we ask Allah's Forgiveness."
