What is the concept of manifesting one's religion for Muslims residing in Western countries, and is it limited to hijab, prayer, and the beard, or does it extend to include raising the adhan, public slaughter, and other practices?

Displaying one's religion means that a Muslim is able to perform the rituals and acts of worship of his religion without embarrassment or exposure to trials. And whoever is persecuted and fears for his religion in a certain country, emigration becomes obligatory upon him to a country where he can feel secure concerning himself and his religion. If he finds Muslim lands, this is preferable. If he does not find them, emigration to lands of disbelief is permissible, provided that he feels secure concerning his religion and himself therein.
