"Nafi narrated to me from Ibn 'Umar, tht the Messenger of Allah said: 'the two parties to a transaction both have the choice so long as they have not separated, or they have chosen." (Sahih)
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَفْتَرِقَا أَوْ يَكُونَ خِيَارًا ‏"‏ ‏.‏
