Musnad Ahmad Hadith 11436

It is narrated from Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Avoid sitting on the roads." The companions (may Allah be pleased with them) said, "O Messenger of Allah (peace and blessings of Allah be upon him)! We cannot do without it; in this way, we chat with each other." The Prophet (peace and blessings of Allah be upon him) said, "If you cannot avoid sitting, then fulfill the rights of the road." The companions (may Allah be pleased with them) asked, "O Messenger of Allah (peace and blessings of Allah be upon him)! What are the rights of the road?" The Prophet (peace and blessings of Allah be upon him) said, "Lowering the gaze, avoiding causing harm, returning greetings, enjoining good, and forbidding evil."
