Sunan An Nasai 4705

أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلَاءِ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ أَنْبَأَنَا ابْنُ إِدْرِيسَ، ‏‏‏‏‏‏عَنْ ابْنِ جُرَيْجٍ، ‏‏‏‏‏‏عَنْ أَبِي الزُّبَيْرِ، ‏‏‏‏‏‏عَنْ جَابِرٍ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ قَضَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالشُّفْعَةِ فِي كُلِّ شَرِكَةٍ لَمْ تُقْسَمْ رَبْعَةٍ وَحَائِطٍ لَا يَحِلُّ لَهُ أَنْ يَبِيعَهُ حَتَّى يُؤْذِنَ شَرِيكَهُ، ‏‏‏‏‏‏فَإِنْ شَاءَ أَخَذَ، ‏‏‏‏‏‏وَإِنْ شَاءَ تَرَكَ، ‏‏‏‏‏‏وَإِنْ بَاعَ وَلَمْ يُؤْذِنْهُ فَهُوَ أَحَقُّ بِهِ .

It was narrated that Jabir said: The Messenger of Allah ruled that pre-emption is to be given in everything that is shared in which the division is not clear, whether it is a house or a garden. It is not permissible to sell it before informing one's partner, who may take it or leave it, as he wishes. He (the share-owner) sells it without informing him, and then he has more right to it.
