Abu Sa'id Al-Khudri, May Allah be pleased with him, said: The Prophet, may the peace and blessings of Allah be upon him, said, "Avoid sitting on roadsides." His Companions said: "O Messenger of Allah, there is no other alternative but to sit there to talk." Thereupon the Messenger of Allah, may the peace and blessings of Allah be upon him, said, "If you insist on that, then fulfill the rights of the road." They asked: "What are their rights?" Thereupon he said, "Lowering the gaze (so that you may not stare at unlawful things); refraining from doing harm to others, responding to the greeting (i.e., saying 'Wa'alaikumus- salam…' to one another) and commanding the good and forbidding the evil."
