You use the phrase "and via such-and-such" in your takhrij (tracing of hadiths to their sources); what do you mean by it?

The student : We read in your books where you say "and in a route" or "and via a route." This term, based on our survey of the takhrij (tracing of hadiths to their sources) of your hadiths, appears in most cases in a specific context, and in every context it conveys a specific meaning. So, Shaykh, may Allah reward you, please give us a brief overview of this term and the contexts in which it is used, because sometimes its meaning is actually confusing.

The Shaykh : There is a difference between one usage and another.
The student: Yes.

The Shaykh : That is why I would like you to provide an example where the confusion occurred.
The student : Very good, Shaykh.

The Shaykh : Because the intended meaning of "and in a route" is like saying "in the chain of narration."
The student: Yes.

The Shaykh : However, the use of the word "route" in a single chain of narration from a single Companion might be, for example, the pivot of the first chain being from Ibn Lahi'ah.
The student: Yes.

The Shaykh : So by saying "and in another route from 'Amr ibn al-Harith," it is the same route mentioned previously.
The student : The same route as Ibn Lahi'ah?

The Shaykh : No, Shaykh, it is indeed Ibn Lahi'ah, meaning he is a supporter (mutabi') of him via 'Amr ibn al-Harith, from Ibn Lahi'ah's teacher, and so on.
The student : Ibn Lahi'ah and the rest of the chain.

The Shaykh: Yes.
The student : This is where this term is placed, saying "and via."

The Shaykh: Yes.
The student : What do you say: "Shaykh, and via Ibn Lahi'ah"?

The Shaykh : And via another route.
The student : And via another route!

The Shaykh : Yes.
