What is the legal implication of mentioning travel (Safar) in the verse regarding pledged security?

Primary text

The mention of travel in the verse concerning pledged security is representative of the common scenario (Makhraj al-Ghalib). This is because a scribe is typically unavailable during travel. This interpretation is further confirmed by the fact that the condition of lacking a scribe is not strictly required for the pledge to be valid, despite being mentioned alongside travel.
