Sahih Bukhari Volume 9, Book 90, Hadith 6978

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ إِنَّمَا جَعَلَ النَّبِيُّ صلى الله عليه وسلم الشُّفْعَةَ فِي كُلِّ مَا لَمْ يُقْسَمْ، فَإِذَا وَقَعَتِ الْحُدُودُ وَصُرِّفَتِ الطُّرُقُ فَلاَ شُفْعَةَ‏.‏ وَقَالَ بَعْضُ النَّاسِ الشُّفْعَةُ لِلْجِوَارِ‏.‏ ثُمَّ عَمَدَ إِلَى مَا شَدَّدَهُ فَأَبْطَلَهُ، وَقَالَ إِنِ اشْتَرَى دَارًا فَخَافَ أَنْ يَأْخُذَ الْجَارُ بِالشُّفْعَةِ، فَاشْتَرَى سَهْمًا مِنْ مِائَةِ سَهْمٍ، ثُمَّ اشْتَرَى الْبَاقِيَ، وَكَانَ لِلْجَارِ الشُّفْعَةُ فِي السَّهْمِ الأَوَّلِ، وَلاَ شُفْعَةَ لَهُ فِي بَاقِي الدَّارِ، وَلَهُ أَنْ يَحْتَالَ فِي ذَلِكَ‏.

Narrated By Jabir bin 'Abdullah : The Prophet has decreed that pre-emption is valid in all cases where the real estate concerned has not been divided, but if the boundaries are established and the ways are made, then there is no pre-emption. A man said, "Pre-emption is only for the neighbour," and then he makes invalid what he has confirmed. He said, "If someone wants to buy a house and being afraid that the neighbour (of the house) may buy it through pre-emption, he buys one share out of one hundred shares of the house and then buys the rest of the house, then the neighbour can only have the right of pre-emption for the first share but not for the rest of the house; and the buyer may play such a trick in this case."
