Sahih Muslim · Book 22: The Book of Musaqah · Pre-emption
Jabir b. 'Abdullah (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying:
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.
