The Messenger of Allah ﷺ as saying: There is the right of option regarding everything which is shared, whether a dwelling or a garden. It is not lawful to sell before informing one's partner, but if he sells without informing him, he has the greatest right to it.  

قَالَ رَسُولُ اللَّهِ ﷺ الشُّفْعَةُ فِي كُلِّ شِرْكٍ رَبْعَةٍ أَوْ حَائِطٍ لاَ يَصْلُحُ أَنْ يَبِيعَ حَتَّى يُؤْذِنَ شَرِيكَهُ فَإِنْ بَاعَ فَهُوَ أَحَقُّ بِهِ حَتَّى يُؤْذِنَهُ  

The Messenger of Allah ﷺ decreed the right to buy the neighboring property applicable to everything which is not divided, but when boundaries are fixed and separate roads made, there is no option.  

إِنَّمَا جَعَلَ رَسُولُ اللَّهِ ﷺ الشُّفْعَةَ فِي كُلِّ مَالٍ لَمْ يُقْسَمْ فَإِذَا وَقَعَتِ الْحُدُودُ وَصُرِفَتِ الطُّرُقُ فَلاَ شُفْعَةَ  

The Prophet ﷺ said: When land has been divided and boundaries have been set up, there is no right of pre-emption in it.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا قُسِّمَتِ الأَرْضُ وَحُدَّتْ فَلاَ شُفْعَةَ فِيهَا  

The Messenger of Allah ﷺ as saying: A neighbor has the best claim to the house or land of the neighbor.  

سَمِعَ النَّبِيَّ ﷺ يَقُولُ الْجَارُ أَحَقُّ بِسَقَبِهِ  

The Prophet ﷺ said: A neighbour has the best claim to the house or land of the neighbour.  

عَنِ النَّبِيِّ ﷺ قَالَ جَارُ الدَّارِ أَحَقُّ بِدَارِ الْجَارِ أَوِ الأَرْضِ  

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.  

قَالَ رَسُولُ اللَّهِ ﷺ الْجَارُ أَحَقُّ بِشُفْعَةِ جَارِهِ يُنْتَظَرُ بِهَا وَإِنْ كَانَ غَائِبًا إِذَا كَانَ طَرِيقُهُمَا وَاحِدًا
