Explanation

The distance between Madina and Khyber is approximately 168/172 kilometers (104 miles) by modern roads.

This aligns with historical Islamic sources that describe Khyber as a 2–3 day journey from Madina.

Khyber was the site of the Battle of Khaybar (628 CE), where Prophet Muhammad (PBUH) led Muslims to victory.

The journey took 3 days on foot/camel, matching the 168 km distance.
