Sahih al-Bukhari, Book 90, Hadith 25 (In-Book) ⓘ

Narrated 'Amr bin Ash-Sharid: Abu Rafi' said that Sa'd offered him four hundred Mithqal of gold for a house. Abu Rafi ' said, "If I had not heard Allah's Messenger saying, 'A neighbor has more right to be taken care of by his neighbor,' then I would not have given it to you." Some people said, "If one has bought a portion of a house and wants to cancel the right of preemption, he may give it as a present to his little son and he will not be obliged to take an oath."

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ إِبْرَاهِيمَ بْنِ مَيْسَرَةَ، عَنْ عَمْرِو بْنِ الشَّرِيدِ، عَنْ أَبِي رَافِعٍ، أَنَّ سَعْدًا، سَاوَمَهُ بَيْتًا بِأَرْبَعِمِائَةِ مِثْقَالٍ فَقَالَ لَوْلاَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ الْجَارُ أَحَقُّ بِصَقَبِهِ ‏" ‏‏.‏ لَمَا أَعْطَيْتُكَ‏.‏ وَقَالَ بَعْضُ النَّاسِ إِنِ اشْتَرَى نَصِيبَ دَارٍ، فَأَرَادَ أَنْ يُبْطِلَ الشُّفْعَةَ، وَهَبَ لاِبْنِهِ الصَّغِيرِ وَلاَ يَكُونُ عَلَيْهِ يَمِينٌ‏.‏
