He goes on to say, “While I was walking one day through the markets of Madinah, and the people’s estrangement had dragged on, I climbed over the wall of Abu Qatadah’s orchard.” In other words, he entered it from above the wall rather than through the gate, as though the gate were closed— and Allah knows best.
