What is the ruling on being away from one's family for a long period?

Question:
This questioner, who used the initials (A. L. B) for his name, says: I would like to inform you that I have been residing in the Kingdom for four years and have not traveled. I have a wife and daughters, and they are in my home country. The reason for this is that I want to earn a livelihood in this blessed land. I work as a salaried employee in a grocery store, and I send them money every month. Do I commit a sin by leaving them for this duration?

Answer:
You should fear sin; because the period is long. What I see is that it is obligatory for you to go to them from time to time. 'Umar (may Allah be pleased with him) set six months as the limit for mujahideen and those who are absent. So, my brother, go to them every six months, or every four months, or something like that, or bring them to you. As for leaving them for this long period, there is great danger for them, and for you as well.
So, it is prescribed for you to leave this matter, and to bring them to you if possible, or to go to them every six months... every four months... every five months. Do not let the period become long. Stay with them for a month... two months, then return to seek sustenance.
So, the result is: it is obligatory for you to take care of this matter, and to be cautious of a long period that may lead them to immorality, or lead you to immorality. There is no power and no strength except with Allah. Yes.

The presenter: May Allah reward you.
