The Prophet ﷺ said: The neighbour is most entitled to the right of pre-emption, and he should wait for its exercise even if he is absent, when the two properties have one road. (Using translation from Abū Dāʾūd 3518)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ الْجَارُ أَحَقُّ بِشُفْعَةِ أَخِيهِ يَنْتَظِرُ وَإِنْ كَانَ غَائِبًا إِذَا كَانَ طَرِيقُهُمَا وَاحِدًا
