Masjid Abu Bakr As-Siddiq

This guide to Masjid Abu Bakr As-Siddiq in Medina goes back to the fifth year after the Hijra, when a Persian companion named Salman al-Farsi proposed defending the city with a trench, an idea the Prophet agreed to try against an army gathered from across Arabia. It follows Abu Bakr and Umar walking that line day after day, checking its depth, and explains why this modest black-and-white mosque carries Abu Bakr's name instead, tied to open ground where the Prophet used to lead Eid prayers. Stand on that same patch of ground while you listen.
