He who has a partner in a dwelling or a garden, it is not lawful for him to sell that until he is permitted by his partner. If he (the partner) agrees, he should go in for that, and if he disapproves of that, he should abandon (the idea of selling it).  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ كَانَ لَهُ شَرِيكٌ فِي رَبْعَةٍ أَوْ نَخْلٍ فَلَيْسَ لَهُ أَنْ يَبِيعَ حَتَّى يُؤْذِنَ شَرِيكَهُ فَإِنْ رَضِيَ أَخَذَ وَإِنْ كَرِهَ تَرَكَ  

Jabir bin 'Abdullah (Allah be pleased with them) said that the Messenger of Allah ﷺ decreed pre-emption in every joint ownership and not divided-the one-it may be a dwelling or a garden. It is not lawful for him (for the partner) to sell that until his partner gives his consent. He (the partner) is entitled to buy it when he desires and he can abandon it if he so likes. And if he (the one partner) sells it without getting the consent of the (other partner), he has the greatest right to it.  

قَضَى رَسُولُ اللَّهِ ﷺ بِالشُّفْعَةِ فِي كُلِّ شِرْكَةٍ لَمْ تُقْسَمْ رَبْعَةٍ أَوْ حَائِطٍ لاَ يَحِلُّ لَهُ أَنْ يَبِيعَ حَتَّى يُؤْذِنَ شَرِيكَهُ فَإِنْ شَاءَ أَخَذَ وَإِنْ شَاءَ تَرَكَ فَإِذَا بَاعَ وَلَمْ يُؤْذِنْهُ فَهْوَ أَحَقُّ بِهِ  

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.  

قَالَ رَسُولُ اللَّهِ ﷺ 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
