مَنْ خَرَجَ فِي طَلَبِ الْعِلْمِ، فَهُوَ فِي سَبِيلِ اللَّهِ حَتَّى يَرْجِعَ
Translation: Whoever goes out seeking knowledge is in the path of Allah until returning.
Source: الترمذي
خَرَجَ is a past-tense verb meaning “went out.” فِي طَلَبِ الْعِلْمِ is a phrase meaning “in pursuit of knowledge.” In فَهُوَ, فَـ introduces the response, while هُوَ is the subject of a nominal statement. فِي سَبِيلِ اللَّهِ supplies the predicate’s meaning, and حَتَّى يَرْجِعَ means “until returning.”
Giving time and sustained effort to beneficial religious learning is a valued way of serving the faith. The report praises seeking knowledge; it does not suggest that every journey or every piece of information has the same religious purpose.
