[Machine] The Messenger of Allah ﷺ said, "The two parties involved in a business transaction have the right to rescind it as long as they have not separated. Hamam said, "I found in my book that the Prophet ﷺ emphasized this three times. If they are truthful and clear in their dealings, they will be blessed in their transaction. But if they lie and conceal, they may gain some profit, but the blessing of their transaction will be destroyed." Hamam said, "I narrated this hadith to Abu Al-Tayyah, who then said, 'I was with Abu Al-Khalil and Abdullah bin Al-Harith narrated this hadith to us. Al-Harith is the narrator.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا قَالَ هَمَّامٌ وَوَجَدْتُ فِي كِتَابِي وَيَخْتَارُ ثَلَاثَ مَرَّاتٍ فَإِنْ صَدَقَا وَبَيَّنَا بُورِكَ لَهُمَا فِي بَيْعِهِمَا وَإِنْ كَذَبَا وَكَتَمَا فَعَسَى أَنْ يَرْبَحَا رِبْحًا وَتُمْحَقَ بَرَكَةُ بَيْعِهِمَا قَالَ هَمَّامٌ فَحَدَّثْتُ بِهَذَا الْحَدِيثِ أَبَا التَّيَّاحِ فَقَالَ كُنْتُ مَعَ أَبِي الْخَلِيلِ فَحَدَّثَنَا عَبْدُ اللهِ بْنُ الْحَارِثِ هَذَا الْحَارِثُ
