He said that God’s Messenger decreed the right of option regarding everything which is shared, whether a dwelling or a garden, when it had not been divided. It is not lawful to sell before informing one’s partner who may take it or let it go as he wishes ; but if he sells without informing him, he has the greatest right to it. Muslim transmitted it.
وَعَنْهُ قَالَ: قَضَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالشُّفْعَةِ فِي كُلِّ شَرِكَةٍ لَمْ تُقْسَمْ رَبْعَةٍ أَوْ حَائِطٍ: «لَا يَحِلُّ لَهُ أَن يَبِيع حَتَّى يُؤذن شَرِيكه فَإِن شَاءَ أَخَذَ وَإِنْ شَاءَ تَرَكَ فَإِذَا بَاعَ وَلَمْ يُؤْذِنْهُ فَهُوَ أَحَقُّ بِهِ» . رَوَاهُ مُسْلِمٌ
