The Prophet ﷺ said, "No deal is settled and finalized unless the buyer and the seller separate, except if the deal is optional (whereby the validity of the bargain depends on the stipulations agreed upon). (Using translation from Bukhārī 2113)  

قَالَ رَسُولُ اللهِ ﷺ «كُلُّ بَيِّعَيْنِ لَا بَيْعَ بَيْنَهُمَا حَتَّى يَتَفَرَّقَا إِلَّا بَيْعَ الْخِيَارِ»  

"When two people meet to engage in trade, the transaction between them is not binding until they separate, unless they have chosen to conclude the transaction." (Using translation from Nasāʾī 4476)  

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ «كُلُّ بَيِّعَيْنِ فَلَا بَيْعَ بَيْنَهُمَا حَتَّى يَتَفَرَّقَا إِلَّا بَيْعَ الْخِيَارِ»

There is no transaction between two persons entering a transaction until they separate, but only when there is an option to annul it. (Using translation from Muslim 1531e)  

قَالَ رَسُولُ اللهِ ﷺ «كُلُّ بَيِّعَيْنِ فَلَا بَيْعَ بَيْنَهُمَا حَتَّى يَتَفَرَّقَا إِلَّا بَيْعَ الْخِيَارِ»

"Two traders have the choice as long as they have not separated, or, they have chosen to conclude the transaction." (Using translation from Nasāʾī 4480)  

عَنِ النَّبِيِّ ﷺ قَالَ «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا أَوْ يَكُونَ بَيْعُهُمَا عَنْ خِيَارٍ»  

"Two trades have the choice as long as until they reach a deal that suits both of them and they confirm it three times. " (Using translation from Nasāʾī 4481)  

«الْبَيِّعَانِ بِالْخِيَارِ حَتَّى يَتَفَرَّقَا أَوْ يَأْخُذَ كُلُّ وَاحِدٍ مِنْهُمَا مِنَ الْبَيْعِ مَا هَوِيَ وَيَتَخَايَرَانِ ثَلَاثَ مِرَارٍ»  

"The Messenger of Allah said;" Two traders have the choice as long as they have not separated, or until they reach a deal that suits both of th4em or that is satisfactory (to both)" (Using translation from Nasāʾī 4482)   

قَالَ رَسُولُ اللهِ ﷺ «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا أَوْ يَأْخُذْ أَحَدُهُمَا مَا رَضِيَ مِنْ صَاحِبِهِ وَمَا هَوِيَ»
