The Messenger of Allah ﷺ as saying: Each one of the two parties in a business has an option (to annul it) against the other party so long as they have not separated, except in a conditional bargain. (Using translation from Abū Dāʾūd 3454)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «الْمُتَبَايِعَانِ كُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ عَلَى صَاحِبِهِ مَا لَمْ يَتَفَرَّقَا إِلَّا بَيْعَ الْخِيَارِ»  

The Messenger of Allah ﷺ said: “The two parties to a transaction have the option (of cancelling it) so long as they have not parted or there is a condition which gives the option to cancel.ʿ (Using translation from Aḥmad 393)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا أَوْ يَكُونَ خِيَارًا»  

"The Messenger of Allah said: 'The two parties to a transaction both have the choice so long as they have not separated, unless they have both chosen to conclude they transaction. If they have both chosen to conclude the transaction, then the transaction is binding." (Sahih ) (Using translation from Nasāʾī 4467)  

قَالَ رَسُولُ اللهِ ﷺ «الْمُتَبَايِعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا إِلَّا أَنْ يَكُونَ الْبَيْعُ كَانَ عَنْ خِيَارٍ فَإِنْ كَانَ الْبَيْعُ عَنْ خِيَارٍ فَقَدْ وَجَبَ الْبَيْعُ»  

"Nafi dictated to me, from Ibn 'Umar who said: The Messenger of Allah said: 'the two parties to a transaction both have the choice so long as they have not separated, unless they have both chosen to conclude the transaction. If they have both chosen to conclude the transaction, then the transactions binding." (Sahih ) (Using translation from Nasāʾī 4468)   

قَالَ رَسُولُ اللهِ ﷺ «إِذَا تَبَايَعَ الْمُبْتَاعَانِ فَكُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ مِنْ بَيْعِهِ مَا لَمْ يَتَفَرَّقَا أَوْ يَكُونَ بَيْعُهُمَا عَنْ خِيَارٍ فَإِنْ كَانَ عَنْ خِيَارِ فَقَدْ وَجَبَ الْبَيْعُ»  

”The two parties to a transaction have the choice (of annulling it) so long as they have not yet parted." (Using translation from Ibn Mājah 2182)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا أَوْ يَقُولَ اخْتَرْ  

"The Messenger of Allah said: 'The two parties to a transaction both have the choice so long as they have not separated or chosen to conclude the transaction." Or perhaps Nafi said: "Or one of them has said to the other: 'Decide! "(Sahih ) (Using translation from Nasāʾī 4470)  

قَالَ رَسُولُ اللهِ ﷺ «الْبَيِّعَانِ بِالْخِيَارِ حَتَّى يَتَفَرَّقَا أَوْ يَكُونَ بَيْعَ خِيَارٍ» وَرُبَّمَا قَالَ نَافِعٌ أَوْ يَقُولَ أَحَدُهُمَا لِلْآخَرِ اخْتَرْ  

"When two men enter into a transaction, each of them has the choice (of annulling it) so long as they have not yet parted and are still together, or one of them has given the option or choice to the other. Once he has accepted the terms of the other, then the transaction is binding. If they part after concluding the transaction and neither of them has rescinded the transaction then the transaction is binding.” (Using translation from Ibn Mājah 2181)  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «إِذَا تَبَايَعَ الرَّجُلَانِ فَكُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ حَتَّى يَتَفَرَّقَا» وَقَالَ مَرَّةً أُخْرَى مَا لَمْ يَتَفَرَّقَا وَكَانَا جَمِيعًا أَوْ خَيَّرَ أَحَدُهُمَا الْآخَرَ فَإِنْ خَيَّرَ أَحَدُهُمَا الْآخَرَ فَتَبَايَعَا عَلَى ذَلِكَ فَقَدْ وَجَبَ الْبَيْعُ وَإِنْ تَفَرَّقَا بَعْدَ أَنْ تَبَايَعَا وَلَمْ يَتْرُكْ وَاحِدٌ مِنْهُمَا الْبَيْعَ فَقَدْ وَجَبَ الْبَيْعُ  

"I heard Nafi narrating from Ibn 'Umar, form the Messenger of Allah 'the two parties to a transaction both have the choice so long as they have not separated unless they have chosen to conclude the transaction. " Nafi said: ''When 'Abdullah bought something he like, he would leave straightaway." (Using translation from Nasāʾī 4473)  

عَنْ رَسُولِ اللهِ ﷺ «أَنَّ الْمُتَبَايِعَيْنِ بِالْخِيَارِ فِي بَيْعِهِمَا مَا لَمْ يَفْتَرِقَا إِلَّا أَنْ يَكُونَ الْبَيْعُ خِيَارًا» قَالَ نَافِعٌ وَكَانَ عَبْدُ اللهِ بْنُ عُمَرَ إِذَا اشْتَرَى شَيْئًا يُعْجِبُهُ فَارَقَ صَاحِبَهُ  

"Nafi narrated to us from Ibn 'Umar, who said: 'The Messenger of Allah said: There is no transaction between the two parties until they separate, unless they have chosen to conclude the transaction."" (Sahih ) (Using translation from Nasāʾī 4474)  

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