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
