Messenger of Allah ﷺ decided the validity of preemption in every joint undivided property, but if the boundaries were well marked or the ways and streets were fixed, then there was no pre-emption.  

قَضَى النَّبِيُّ ﷺ بِالشُّفْعَةِ فِي كُلِّ مَالٍ لَمْ يُقْسَمْ فَإِذَا وَقَعَتِ الْحُدُودُ وَصُرِّفَتِ الطُّرُقُ فَلاَ شُفْعَةَ  

the same as above but said, "... in every joint undivided thing..." Narrated Hisham from Maʿmar the same as above but said, " ... in every property... "  

وَقَالَ فِي كُلِّ مَا لَمْ يُقْسَمْ
