Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ أَبِي يَحْيَى عَنِ ابْنِ عَبَّاسٍ أَنَّ رَجُلَيْنِ اخْتَصَمَا إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَسَأَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْمُدَّعِيَ الْبَيِّنَةَ فَلَمْ يَكُنْ لَهُ بَيِّنَةٌ فَاسْتَحْلَفَ الْمَطْلُوبَ فَحَلَفَ بِاللَّهِ الَّذِي لَا إِلَهَ إِلَّا هُوَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّكَ قَدْ فَعَلْتَ وَلَكِنْ غُفِرَ لَكَ بِإِخْلَاصِكَ قَوْلَ لَا إِلَهَ إِلَّا اللَّهُ.
English Translation
Two men brought a dispute to the Prophet (peace be upon him). The Prophet asked the claimant for evidence, but he had no evidence. So he asked the defendant to take an oath. He swore by Allah, besides whom there is no deity. The Messenger of Allah (peace be upon him) said: 'You have indeed done it (sworn falsely), but you have been forgiven because of your sincere utterance of La ilaha illallah.'
