Is it prescribed to leave one's family and children for long periods for the sake of calling people to Allah?

Question:
Your Eminence the Shaykh, the questioner says: Some people travel and leave their belongings and their families for months at a time to go out calling people to Allah, and they say to their children, "It is Allah." Is this action prescribed?

Answer:
It is obligatory for a person to care for his family and attend to them, and he should not travel unless he has attended to them and secured their needs. Otherwise, he should not travel, neither for da'wah nor for anything else. He must look after his dependents and his household, protect them, and safeguard them. He should attend the circles of knowledge and call people to Allah in his own place, in his own town. As for neglecting his family and going here and there, that is not permissible.
