Which is better: living in a Muslim country where one is subjected to injustice from all sides, or migrating to a non-Muslim country to live with dignity? And what is the ruling on imposing taxes on the poor?

A Muslim's emigration to a land of disbelief is dangerous for his faith and his offspring, and residence in Islamic countries is more befitting. Emigration to lands of disbelief may be permissible out of necessity, provided certain conditions are met: being able to perform the rituals of religion, being safe from temptation (fitna), and raising children in an Islamic manner. If residence in an Islamic country is not feasible, then one should search for another Muslim country that provides these conditions, rather than emigrating directly to non-Muslim lands. As for taxes, that requires a detailed explanation.
