Ikrimah (may Allah have mercy on him) says: I heard Sayyiduna Abu Hurayrah (may Allah be pleased with him) say that the Messenger of Allah (peace and blessings be upon him) judged: "A neighbour may place his beams on his neighbour's wall if he wishes, even if he (the neighbour) refuses."
And he heard that the Messenger of Allah (peace and blessings be upon him) judged: "If people dispute over a road, fix the road at seven cubits."
