If the husband travels for more than four months and refuses to return, does the matter fall under the ruling of ila'?

Question:
Honorable Shaykh, may Allah grant you success, what is the ruling if the husband is traveling for more than four months and refuses to return to his country and to his wife? Does this fall under the ruling of one who has sworn an oath of abstinence (ila')?

Answer:
If he has an excuse for not returning, he is excused in this because he is unable to return. But if he has no excuse, and she has requested his arrival and he refused, then he is not allowed to do that. If she demands his arrival, it is obligatory for him to come to her. Yes.
