What is the meaning of "and he walked and did not ride" in the context of the Friday sermon, and does walking apply to going only or does it include both going and returning?

The aforementioned Hadith is authentic, narrated by Imam Ahmad and Abu Dawud, and authenticated by Al-Albani. The virtue of walking to acts of worship for those capable has been previously explained. As for returning, one has the choice between riding and walking.
