The Prophet ﷺ sent Khalid ibn al-Walid to Ukaydir of Dumah. He was seized and they brought him to him (i.e. the Prophet). He spared his life and made peace with him on condition that he should pay jizyah (poll-tax).  

أَنَّ النَّبِيَّ ﷺ بَعَثَ خَالِدَ بْنَ الْوَلِيدِ إِلَى أُكَيْدِرِ دُومَةَ فَأُخِذَ فَأَتَوْهُ بِهِ فَحَقَنَ لَهُ دَمَهُ وَصَالَحَهُ عَلَى الْجِزْيَةِ  

When the Prophet ﷺ sent him to the Yemen, he ordered to take from everyone who had reached puberty one dinar or its equivalent in Mu'afiri garment of Yemen origin.  

أَنَّ النَّبِيَّ ﷺ لَمَّا وَجَّهَهُ إِلَى الْيَمَنِ أَمَرَهُ أَنْ يَأْخُذَ مِنْ كُلِّ حَالِمٍ يَعْنِي مُحْتَلِمًا دِينَارًا أَوْ عِدْلَهُ مِنَ الْمَعَافِرِيِّ ثِيَابٌ تَكُونُ بِالْيَمَنِ  

A simiar tradition from the Prophet ﷺ has also been transmitted by Mu’adh through a different chain of narrators.  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ  

‘Ali said “If I survive for the Christians of Banu Taghlib I shall kill fighters and captivate children for I had written a document between them and the Prophet ﷺ to the effect that they would not make their children Christian. Abu Dawud said “This is rejected (munkar) tradition and it has reached me from Ahmad (bin Hanbal) that he used to reject this tradition seriously. Abu ‘Ali said “Abu Dawud did not present this (tradition) in this second reading.”  

عَلِيٌّ لَئِنْ بَقِيتُ لِنَصَارَى بَنِي تَغْلِبَ لأَقْتُلَنَّ الْمُقَاتِلَةَ وَلأَسْبِيَنَّ الذُّرِّيَّةَ فَإِنِّي كَتَبْتُ الْكِتَابَ بَيْنَهُمْ وَبَيْنَ النَّبِيِّ ﷺ عَلَى أَنْ لاَ يُنَصِّرُوا أَبْنَاءَهُمْ  

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.  

صَالَحَ رَسُولُ اللَّهِ ﷺ 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
