Question: If a person is vulnerable and cannot feel safe from temptation in his country, is hijrah obligatory on the Muslim in this case, and to where should he migrate?
Answer: Praise be to Allaah.
If the situation is as you describe, and a Muslim feels vulnerable with regard to himself and his religious commitment in the face of temptations in his own country, then it is prescribed for him to migrate – if he can – to a land where he will feel safe.
And Allaah is the source of strength. May Allaah bless our Prophet Muhammad and his family and companions, and grant them peace.
