What is the ruling on residing in Australia and acquiring its citizenship, knowing that this country participates in the war in Afghanistan and Iraq, given that the questioner is a young Palestinian who immigrated for academic achievement and self-development without intending to abandon his homeland?

It is not permissible for a Muslim to obtain citizenship from a disbelieving country, as this leads to showing loyalty to them and assenting to their falsehood. As for residing without citizenship, the default rule is prohibition, based on the words of Allah Almighty: "Indeed, those whom the angels take [in death] while wronging themselves - [the angels] will say, 'In what [condition] were you?' They will say, 'We were oppressed in the land.' They will say, 'Was not the earth of Allah spacious enough for you to emigrate therein?' Such A those whose refuge is Hell - and what an evil destination!" and based on the words of the Prophet, peace and blessings be upon him: "I am free of any Muslim who resides among the polytheists," unless the residence is for inviting people to Islam without fear of temptation. Some scholars have made exceptions for certain situations of naturalization or residence, for an overriding benefit or out of necessity.
