Hadith 35:3
Malik said that he heard that Said ibn al-Musayyab, when asked about pre-emption and whether there was a sunna in it, said, "Yes. Pre-emption is in houses and land, and it is only between partners."
قَالَ مَالِكٌ إِنَّهُ بَلَغَهُ أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ سُئِلَ عَنِ الشُّفْعَةِ هَلْ فِيهَا مِنْ سُنَّةٍ فَقَالَ نَعَمْ الشُّفْعَةُ فِي الدُّورِ وَالأَرَضِينَ وَلاَ تَكُونُ إِلاَّ بَيْنَ الشُّرَكَاءِ
