Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ هِشَامٍ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنْ سَمُرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا.
English Translation
Abd al-Rahman ibn Mahdi told us, from Hisham, from Qatadah, from al-Hasan, from Samurah, who said: The Messenger of Allah, peace and blessings be upon him, said: The two parties to a sale have the option (to cancel) as long as they have not separated.
