"I heard the Messenger of Allah say: 'If the two parties to a transaction disagree, and neither of them has any proof, then it is as the owner of the goods says, or they may cancel it.''' (Using translation from Nasāʾī 4648)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا اخْتَلَفَ الْبَيِّعَانِ وَلَيْسَ بَيْنَهُمَا بَيِّنَةٌ فَالْقَوْلُ مَا يَقُولُ صَاحِبُ السِّلْعَةِ أَوْ يَتَرَادَّانِ  

"I heard the Messenger of Allah say: 'If the two parties to a transaction disagree, and neither of them has any proof, then it is as the owner of the goods says, or they may cancel it.''' (Using translation from Nasāʾī 4648)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا اخْتَلَفَ الْبَيِّعَانِ وَلَيْسَ بَيْنَهُمَا بَيِّنَةٌ فَهُوَ مَا يَقُولُ رَبُّ السِّلْعَةِ أَوْ يَتْرُكَا»  

"I heard the Messenger of Allah say: 'If the two parties to a transaction disagree, and neither of them has any proof, then it is as the owner of the goods says, or they may cancel it.''' (Using translation from Nasāʾī 4648)   

"إذا اختلف البيِّعانِ وليس بينهما بيِّنةٌ، فهو ما يقولُ ربُّ السِّلْعَةِ أو يتتاركان" .
