Ruling on leaving one's family and going out to renew one's faith

Question:
Is it prescribed to leave one's children with the wife and go out to renew one's faith?

Answer:
One should do what is best. If going out does not harm them, there is no harm in traveling. If his going out harms them, then striving with them is more appropriate, to teach them, guide them, direct them, and protect them from evil.
As for if his going out does not harm them, and they have someone to take his place, or their mother is good and can take his place, there is no harm.
