حَدَّثَنَا مُصَرِّفُ بْنُ عَمْرٍو الْيَامِيُّ، حَدَّثَنَا يُونُسُ، - يَعْنِي ابْنَ بُكَيْرٍ - حَدَّثَنَا أَسْبَاطُ بْنُ نَصْرٍ الْهَمْدَانِيُّ، عَنْ إِسْمَاعِيلَ بْنِ عَبْدِ الرَّحْمَنِ الْقُرَشِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ صَالَحَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَهْلَ نَجْرَانَ عَلَى أَلْفَىْ حُلَّةٍ النِّصْفُ فِي صَفَرٍ وَالْبَقِيَّةُ فِي رَجَبٍ يُؤَدُّونَهَا إِلَى الْمُسْلِمِينَ وَعَارِيَةِ ثَلاَثِينَ دِرْعًا وَثَلاَثِينَ فَرَسًا وَثَلاَثِينَ بَعِيرًا وَثَلاَثِينَ مِنْ كُلِّ صِنْفٍ مِنْ أَصْنَافِ السِّلاَحِ يَغْزُونَ بِهَا وَالْمُسْلِمُونَ ضَامِنُونَ لَهَا حَتَّى يَرُدُّوهَا عَلَيْهِمْ إِنْ كَانَ بِالْيَمَنِ كَيْدٌ أَوْ غَدْرَةٌ عَلَى أَنْ لاَ تُهْدَمَ لَهُمْ بَيْعَةٌ وَلاَ يُخْرَجُ لَهُمْ قَسٌّ وَلاَ يُفْتَنُوا عَنْ دِينِهِمْ مَا لَمْ يُحْدِثُوا حَدَثًا أَوْ يَأْكُلُوا الرِّبَا ‏.‏ قَالَ إِسْمَاعِيلُ فَقَدْ أَكَلُوا الرِّبَا ‏.‏ قَالَ أَبُو دَاوُدَ إِذَا نَقَضُوا بَعْضَ مَا اشْتَرَطَ عَلَيْهِمْ فَقَدْ أَحْدَثُوا ‏.‏

The Messenger of Allah (ﷺ) concluded peace with the people of Najran on condition that they would pay to Muslims two thousand suits of garments, half of Safar, and the rest in Rajab, and they would lend (Muslims) thirty coats of mail, thirty horses, thirty camels, and thirty weapons of each type used in battle. Muslims will stand surely for them until they return them in case there is any plot or treachery in the Yemen. No church of theirs will be demolished and no clergyman of theirs will be turned out. There will be no interruption in their religion until they bring something new or take usury. Isma'il said: They took usury. Abu Dawud said: If they violate any provision of the treaty, they will be deemed as bringing something new.
