Avoid the sittings of the pathways." We said: "O Messenger of Allah, we did not sit for anything harmful; we sat to discuss and talk." He said: "If you must, then give it its right." We said: "O Messenger of Allah, and what is its right?" He said: "Lowering the gaze, returning the greeting, and good speech."
