مُسْنَدُ أَبِي عَبْدِ الرَّحْمَنِ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا
Three-Narrator Ahadith 7
ʿAbdullāh ibn Dīnār said:
I heard ʿAbdullāh ibn ʿUmar (رضي الله عنهما) say: ‘I heard the Prophet (ﷺ) say: “The two parties to a sale have the right of cancellation (khiyār al-majlis) so long as they have not parted, or unless it is a stipulated option sale (bayʿ khiyār).”‘ Reference: Musnad Aḥmad 7
حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، قَالَ: سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا، أَوْ يَكُونَ بَيْعَ خِيَارٍ.»
