Narrated 'Amr bin Shu'aib on his father's authority from his grandfather (RA):

The Prophet (ﷺ) said: "The two parties (seller and buyer) in a business transaction have a choice (to annul it) until they separated (from one another), unless it is a transaction with the right to annul it attached to it; and it is not allowed for one to separated from the other for fear that he may cancel the deal." [Reported by al-Khamsah except Ibn Majah. ad-Daraqutni, Ibn Khuzaimah and Ibn al-Jarud also reported it].

وَعَنْ عَمْرِو بْنِ شُعَيْبٍ, عَنْ أَبِيهِ, عَنْ جَدِّهِ; أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-قَالَ: { اَلْبَائِعُ وَالْمُبْتَاعُ بِالْخِيَارِ حَتَّى يَتَفَرَّقَا, إِلَّا أَنْ تَكُونَ صَفْقَةَ [1]‏ خِيَارٍ, وَلَا يَحِلُّ لَهُ أَنْ يُفَارِقَهُ خَشْيَةَ أَنْ يَسْتَقِيلَهُ } رَوَاهُ اَلْخَمْسَةُ إِلَّا اِبْنَ مَاجَهْ, وَاَلدَّارَقُطْنِيُّ, وَابْنُ خُزَيْمَةَ, وَابْنُ اَلْجَارُودِ [2]‏ .‏
