[Machine] The Prophet ﷺ said, "None of you should sell anything over the sale of another. In the narration of Abu Zakariyya, he said, 'None of you should sell.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لَا يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَفِي رِوَايَةِ أَبِي زَكَرِيَّا لَا يَبِيعُ  

[Machine] "That the Messenger of Allah ﷺ said, 'None of you should sell upon the sale of his brother, nor propose to the betrothed of his brother, except with his permission.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَبِيعَنَّ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ إِلَّا بِإِذْنِهِ  

[Machine] "From the Prophet ﷺ, he said: 'Do not compete in prices, nor should one who has already made an offer sell his goods to someone else, and a man should not propose to a woman who has already been proposed to. And a woman should not ask for her sister's divorce in order to take what is in her possession.' And Abu 'Abdullah Al-Hafiz narrated to us, and Abu 'Amr ibn Abi Ja'far narrated to me, and I am Abu Ya'la narrated to 'Amr ibn Muhammad Al-Naqid, who narrated from Sufyan, and he mentioned it with its chain of narration, with the exception that he said that the Prophet ﷺ conveyed it, and he added: 'And a man should not name a price for his brother's offer.' This was narrated by Al-Bukhari in his Sahih from 'Ali ibn Al-Madini, and it was narrated by Muslim from Zuhair ibn Harb and others from Sufyan, and it was also narrated by 'Amr ibn Muhammad Al-Naqid with an addition."  

عَنِ النَّبِيِّ ﷺ قَالَ لَا تَنَاجَشُوا وَلَا يَبِعْ حَاضِرٌ لِبَادٍ وَلَا يَبِعِ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَتِهِ وَلَا تَسْأَلِ الْمَرْأَةُ طَلَاقَ أُخْتِهَا لِتُكْفِئَ مَا فِي إِنَائِهَا 10891 وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أَخْبَرَنِي أَبُو عَمْرِو بْنُ أَبِي جَعْفَرٍ أنا أَبُو يَعْلَى ثنا عَمْرُو بْنُ مُحَمَّدٍ النَّاقِدُ ثنا سُفْيَانُ فَذَكَرَهُ بِإِسْنَادِهِ نَحْوَهُ إِلَّا أَنَّهُ قَالَ يَبْلُغُ بِهِ النَّبِيَّ ﷺ وَزَادَ وَلَا يَسُمِ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَرَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ عَلِيِّ بْنِ الْمَدِينِيِّ وَرَوَاهُ مُسْلِمٌ عَنْ زُهَيْرِ بْنِ حَرْبٍ وَغَيْرِهِ عَنْ سُفْيَانَ وَرَوَاهُ أَيْضًا عَنْ عَمْرِو بْنِ مُحَمَّدٍ النَّاقِدِ بِزِيَادَتِهِ  

[Machine] "That the Messenger of Allah ﷺ said: 'None of you should sell something that another person has already bought.' This is narrated in Sahih Hadith of Malik, and Imam Shafi'i (may Allah have mercy on him) also endorsed it. It applies to anyone who buys an item from someone, and they have not separated (from each other) until another person comes to him and offers him the same item or something better than it at a lower price. In this case, the seller can revoke the sale because he still has the option before the separation. If this happens, it will be considered corruption, even though Allah has forbidden disobedience when one has knowledge of the Hadith, and the sale in this case becomes obligatory."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ مَالِكٍ وَقَدْ حَمَلَهُ الشَّافِعِيُّ رَحِمَهُ اللهُ عَلَى مَنِ اشْتَرَى مِنْ رَجُلٍ سِلْعَةً فَلَمْ يَتَفَرَّقَا حَتَّى أَتَاهُ آخَرُ فَعَرَضَ عَلَيْهِ مِثْلَ سِلْعَتِهِ أَوْ خَيْرًا مِنْهَا بِأَقَلَّ مِنَ الثَّمَنِ فَيَفْسَخُ بَيْعَ صَاحِبِهِ فَإِنَّ لَهُ الْخِيَارَ قَبْلَ التَّفَرُّقِ فَيَكُونُ هَذَا فَسَادًا وَقَدْ عَصَى اللهَ إِذَا كَانَ بِالْحَدِيثِ عَالِمًا وَالْبَيْعُ فِيهِ لَازِمٌ
