Arabic hadith text
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، وَحُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ الرُّؤَاسِيُّ، عَنْ مُغِيرَةَ بْنِ زِيَادٍ، عَنْ عُبَادَةَ بْنِ نُسَىٍّ، عَنِ الأَسْوَدِ بْنِ ثَعْلَبَةَ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، قَالَ عَلَّمْتُ نَاسًا مِنْ أَهْلِ الصُّفَّةِ الْكِتَابَ وَالْقُرْآنَ فَأَهْدَى إِلَىَّ رَجُلٌ مِنْهُمْ قَوْسًا فَقُلْتُ لَيْسَتْ بِمَالٍ وَأَرْمِي عَنْهَا فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ لآتِيَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم فَلأَسْأَلَنَّهُ فَأَتَيْتُهُ فَقُلْتُ يَا رَسُولَ اللَّهِ رَجُلٌ أَهْدَى إِلَىَّ قَوْسًا مِمَّنْ كُنْتُ أُعَلِّمُهُ الْكِتَابَ وَالْقُرْآنَ وَلَيْسَتْ بِمَالٍ وَأَرْمِي عَنْهَا فِي سَبِيلِ اللَّهِ ‏.‏ قَالَ ‏"‏إِنْ كُنْتَ تُحِبُّ أَنْ تُطَوَّقَ طَوْقًا مِنْ نَارٍ فَاقْبَلْهَا ‏"‏ ‏.‏
Translation
Narrated Ubaydah ibn as-Samit

I taught some people among the people of Suffah writing and the Quran. A man of them presented a bow to me, and I said: 'It is not wealth, and I will shoot with it in the cause of Allah, the Mighty and Majestic. I will indeed go to the Messenger of Allah (ﷺ) and ask him.' So I came to him and said: 'O Messenger of Allah, a man whom I was teaching writing and the Quran presented a bow to me, and it is not wealth, and I shoot with it in the cause of Allah.' He said: 'If you would like to be collared with a collar of fire, then accept it.'
