وَعَن حَكِيم بن حزَام
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا فَإِنْ صَدَقَا وَبَيَّنَا بُوِرَكَ لَهُمَا فِي بَيْعِهِمَا وَإِنْ كَتَمَا وَكَذَبَا مُحِقَتْ بَرَكَةُ بَيْعِهِمَا»
Hakim ibn Hizam reported God’s Messenger as saying, “Both parties in a business transaction have a right to annul it so long as they have not separated; and if they tell the truth and make everything clear they will be blessed in their transaction, but if they conceal anything and lie the blessing on their transaction will be blotted out.”
