Sunan Abi Dawud, Hadith 3459 ⓘ

Narrated Hakim b. Hizam: The Messenger of Allah as saying: Both parties in a business transaction have a right of option (to annul it) so long as they are not separated ; and if they tell the truth and make everything clear, they will be blessed in their transaction, but it they conceal anything and lie, the blessing on their transaction will be blotted out. Abu Dawud said: A similar tradition has also been transmitted by Sa'id b. Abi 'Arubah and Hammad. As regards with Hammam, he said in his version: Until they separate or exercise the right of option (to annul the transaction), saying the words of option three times.

حَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَبِي الْخَلِيلِ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، عَنْ حَكِيمِ بْنِ حِزَامٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَفْتَرِقَا فَإِنْ صَدَقَا وَبَيَّنَا بُورِكَ لَهُمَا فِي بَيْعِهِمَا وَإِنْ كَتَمَا وَكَذَبَا مُحِقَتِ الْبَرَكَةُ مِنْ بَيْعِهِمَا ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ وَكَذَلِكَ رَوَاهُ سَعِيدُ بْنُ أَبِي عَرُوبَةَ وَحَمَّادٌ وَأَمَّا هَمَّامٌ فَقَالَ ‏"‏ حَتَّى يَتَفَرَّقَا أَوْ يَخْتَارَ ‏"‏ ‏.‏ ثَلاَثَ مِرَارٍ ‏.‏
