Sahih Muslim 1608cBook 22, Hadith 168
وَحَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا ابْنُ وَهْبٍ، عَنِ ابْنِ جُرَيْجٍ، أَنَّ أَبَا الزُّبَيْرِ، أَخْبَرَهُ أَنَّهُ، سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الشُّفْعَةُ فِي كُلِّ شِرْكٍ فِي أَرْضٍ أَوْ رَبْعٍ أَوْ حَائِطٍ لاَ يَصْلُحُ أَنْ يَبِيعَ حَتَّى يَعْرِضَ عَلَى شَرِيكِهِ فَيَأْخُذَ أَوْ يَدَعَ فَإِنْ أَبَى فَشَرِيكُهُ أَحَقُّ بِهِ حَتَّى يُؤْذِنَهُ " .
There is pre-emption in everything which is shared, be it land, or a dwelling or a garden. It is not proper to sell it until he informs his partner; he may go in for that, or he may abandon it; and it he (the partner intending to sell his share) does not do that, then his partner has the greatest right to it until he permits him.
