حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ حَدَّثَنَا شَرِيكٌ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ أَبِي يَحْيَى الْأَعْرَجِ عَنِ ابْنِ عَبَّاسٍ قَالَ اخْتَصَمَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَجُلَانِ فَوَقَعَتْ الْيَمِينُ عَلَى أَحَدِهِمَا فَحَلَفَ بِاللَّهِ الَّذِي لَا إِلَهَ إِلَّا هُوَ مَا لَهُ عِنْدَهُ شَيْءٌ قَالَ فَنَزَلَ جِبْرِيلُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ إِنَّهُ كَاذِبٌ إِنَّ لَهُ عِنْدَهُ حَقَّهُ فَأَمَرَهُ أَنْ يُعْطِيَهُ حَقَّهُ وَكَفَّارَةُ يَمِينِهِ مَعْرِفَتُهُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَوْ شَهَادَتُهُ
مسند امام احمد بن حنبل · Hadith 2695
It was narrated that Ibn 'Abbas (RA) said: Two men referred a dispute to the Messenger of Allah (PBUH) and one of them had to swear an oath, so he swore by Allah besides Whom there is no other god that he did not owe anything [to the other man]. Then Jibreel came to the Prophet (PBUH) and said: He is lying; he does owe him some- thing. So he told him to give him his dues, and the expiation for breaking his oath was his affirming that there was no god except Allah, or his shahadah.
