عَنْ جَابِرٍ قَالَ: قَضَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالشُّفْعَةِ فِي كُلِّ مَا لَمْ يُقْسَمْ فَإِذَا وَقَعَتِ الْحُدُودُ وَصُرِفَتِ الطُّرُقُ فَلَا شُفْعَة. رَوَاهُ البُخَارِيّ

Abu Huraira reported God’s Messenger as saying, “One must not prevent his neighbour from fixing a beam in his wall.” (Bukhari and Muslim.)
