It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "None of you should prevent his neighbour from placing wood on his wall; and when you disagree about a road, make it seven cubits wide."
The narration of Ayyub, Khalid and al-Zubayr is more authentic, and Allah knows best.
