Arabic (Original)
حَدَّثَنَا عَبْد اللَّهِ قَالَ قَرَأْتُ عَلَى أَبِي حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ ابْنِ عَجْلَانَ قَالَ حَدَّثَنِي عَوْنُ بْنُ عَبْدِ اللَّهِ عَنِ ابْنِ مَسْعُودٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِذَا اخْتَلَفَ الْبَيِّعَانِ فَالْقَوْلُ مَا قَالَ الْبَائِعُ وَالْمُبْتَاعُ بِالْخِيَارِ.
English Translation
Abdullah said: I read to my father: Yahya ibn Sa'id told us, from Ibn Ajlan, who said: Awn ibn Abdullah told me, from Ibn Mas'ud, who said: I heard the Messenger of Allah (peace and blessings be upon him) say, "When the two parties to a sale disagree, the word is what the seller says, and the buyer has the choice."
