Sahih al-Bukhari 6980
Narrated Abu Rafi`:
The Prophet (ﷺ) said, "The neighbor has more right to be taken care of by his neighbor (than anyone 
else)." Some men said, "If one wants to buy a house for 20,000 Dirhams then there is no harm to play 
a trick to deprive somebody of preemption by buying it (just on paper) with 20,000 Dirhams but 
paying to the seller only 9,999 Dirhams in cash and then agree with the seller to pay only one Dinar in 
cash for the rest of the price (i.e. 10,001 Dirhams). If the preemptor offers 20,000 Dirhams for the 
house, he can buy it otherwise he has no right to buy it (by this trick he got out of preemption). If the 
house proves to belong to somebody else other than the seller, the buyer should take back from the 
seller what he has paid, i.e., 9,999 Dirhams and one Dinar, because if the house proves to belong to 
somebody else, so the whole bargain (deal) is unlawful. If the buyer finds a defect in the house and it 
does not belong to somebody other than the seller, the buyer may return it and receive 20,000 Dirhams 
(instead of 9999 Dirham plus one Dinar) which he actually paid.' Abu `Abdullah said, "So that man 
allows (some people) the playing of tricks amongst the Muslims (although) the Prophet (ﷺ) said, 'In 
dealing with Muslims one should not sell them sick (animals) or bad things or stolen things."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ إِبْرَاهِيمَ بْنِ مَيْسَرَةَ، عَنْ عَمْرِو بْنِ الشَّرِيدِ، عَنْ أَبِي رَافِعٍ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ الْجَارُ أَحَقُّ بِصَقَبِهِ ‏"‏‏.‏ وَقَالَ بَعْضُ النَّاسِ إِنِ اشْتَرَى دَارًا بِعِشْرِينَ أَلْفَ دِرْهَمٍ، فَلاَ بَأْسَ أَنْ يَحْتَالَ حَتَّى يَشْتَرِيَ الدَّارَ بِعِشْرِينَ أَلْفَ دِرْهَمٍ، وَيَنْقُدَهُ تِسْعَةَ آلاَفِ دِرْهَمٍ وَتِسْعَمِائَةَ دِرْهَمٍ وَتِسْعَةً وَتِسْعِينَ، وَيَنْقُدَهُ دِينَارًا بِمَا بَقِيَ مِنَ الْعِشْرِينَ الأَلْفَ، فَإِنْ طَلَبَ الشَّفِيعُ أَخَذَهَا بِعِشْرِينَ أَلْفَ دِرْهَمٍ، وَإِلاَّ فَلاَ سَبِيلَ لَهُ عَلَى الدَّارِ، فَإِنِ اسْتُحِقَّتِ الدَّارُ، رَجَعَ الْمُشْتَرِي عَلَى الْبَائِعِ بِمَا دَفَعَ إِلَيْهِ، وَهْوَ تِسْعَةُ آلاَفِ دِرْهَمٍ وَتِسْعُمِائَةٍ وَتِسْعَةٌ وَتِسْعُونَ دِرْهَمًا وَدِينَارٌ، لأَنَّ الْبَيْعَ حِينَ اسْتُحِقَّ انْتَقَضَ الصَّرْفُ فِي الدِّينَارِ، فَإِنْ وَجَدَ بِهَذِهِ الدَّارِ عَيْبًا وَلَمْ تُسْتَحَقَّ، فَإِنَّهُ يَرُدُّهَا عَلَيْهِ بِعِشْرِينَ أَلْفَ دِرْهَمٍ‏.‏ قَالَ فَأَجَازَ هَذَا الْخِدَاعَ بَيْنَ الْمُسْلِمِينَ وَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ دَاءَ وَلاَ خِبْثَةَ وَلاَ غَائِلَةَ ‏"‏‏.‏
