Is the head of the household sinful for neglecting the upbringing of his children due to his preoccupation with seeking a livelihood?

Question:
A questioner says that he lives in one town while his family and children live in another, and he does not see them except on Wednesdays, Thursdays, and Fridays. Is he sinful, especially regarding the issue of their upbringing and their not receiving sufficient education?

Answer:
If you can take them with you and house them with you in the town where you work and raise them, that is obligatory upon you. If this is not feasible, then you leave them in their town and you go to seek a livelihood, but you correspond with them and visit them from time to time. Also, if he has a relative, may Allah preserve him, among his brothers, uncles, or relatives, he should instruct them to look after them and monitor them in his absence.
