The Ruling on Traveling Abroad to Seek Knowledge

Question:
I am working in the field of principles of jurisprudence, and there are surgical courses outside the Kingdom in the field of [Kaf], so is it permissible for me to benefit from these courses, or are they in [Arida]?

Answer:
If these courses contain information that is not available in the lands of the Muslims and the Muslims need it, then there is no harm in traveling to learn it in order to meet the needs of the Muslims. However, if this knowledge is available in the lands of the Muslims, it is not permissible for you to travel abroad to study it when it is available in the lands of the Muslims. Or, if this knowledge is not available in the lands of the Muslims but the Muslims do not need it—matters of idle curiosity that are not needed—then this does not meet the condition, because traveling to the lands of the polytheists is forbidden except in matters that have been exempted, and among them is traveling to learn what the Muslims need and which is not available in their lands. Yes, yes.
