Sunan Abi Dawud 3416
Narrated Ubaydah ibn as-Samit:
I taught some persons of the people of Suffah writing and the Qur'an. A man of them presented to me a bow. I said: It cannot be reckoned  property; may I shoot with it in Allah's path? I must come to the Apostle of of Allah (ﷺ) and ask him (about it). So I came to him and said : Messenger of Allah (ﷺ), one of those whom I have been teaching writing and the Qur'an has presented me a bow, and as it cannot be reckoned property, may I shoot with it in Allah's path? He said: If you want to have a necklace of fire on you, accept it.
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 ‏"‏ ‏.‏
