Is it better to stay in Turkey or to go to non-Muslim countries for a better livelihood?

It is better to live in a place that helps one establish their religion and obey Allah, even if the salary and standard of living are lower, as long as it covers basic needs, because the hereafter is better and more lasting. The majority of scholars do not prohibit residing in non-Muslim lands if one is safe from temptation and is able to practice the rituals of their religion.
