Mishkat al-Masabih 11 Business Transactions كتاب البيوع 43

عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا إِلَّا أَنْ يَكُونَ صَفْقَةَ خِيَارٍ وَلَا يَحِلُّ لَهُ أَنْ يُفَارِقَ صَاحِبَهُ خَشْيَةَ أَنْ يَسْتَقِيلَهُ» . رَوَاهُ التِّرْمِذِيّ وَأَبُو دَاوُد وَالنَّسَائِيّ

‘Amr b. Shu’aib, on his father’s authority, said that his grandfather 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 unless it is a bargain with the right to annul it attached to it; and one has not the right to separate from the other for fear that he may demand that the bargain be rescinded.” Tirmidhi, Abu Dawud and Nasa’i transmitted it.
