Is
      hijrah obligatory for those who feel vulnerable in their religion?
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?
Praise be to Allah.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.
