The ruling on a husband being absent from his wife due to work circumstances and the permissible duration

Question:
This questioner, Zaghloul, is an Egyptian working in Riyadh. He says in this question: I am newly married, having spent approximately forty days with my wife after the marriage. Due to my commitments and work circumstances, I traveled and left her, after seeking her permission to travel. Have I sinned by doing this? And what is the duration permissible by the Shari'ah for a husband who is absent from his wife?

Answer:
The woman has the right to intimacy and chastity, and that her husband not be absent from her for a duration that harms her. She also has the right to financial maintenance, housing, and companionship with her husband. However, if necessity calls for him to travel away from her to seek a livelihood, to seek knowledge, or for other permissible, necessary, or needed purposes, there is no harm in his traveling, because this is something that is unavoidable and necessity calls for it. But he must return to her from time to time whenever he is able to do so. The maximum duration a husband may be absent from his wife is four months. Yes.
