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. (Using translation from Bukhārī 2214)
أَنَّ رَسُولَ اللهِ ﷺ قَضَى بِالشُّفْعَةِ فِيمَا لَمْ يُقْسَمْ فَإِذَا وَقَعَتِ الْحُدُودُ فَلَا شُفْعَةَ
