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. (Using translation from Abū Dāʾūd 3416)
عَلَّمْتُ نَاسًا مِنْ أَهْلِ الصُّفَّةِ الْكِتَابَةَ وَالْقُرْآنَ وَأَهْدَى إِلَيَّ رَجُلٌ مِنْهُمْ قَوْسًا فَقُلْتُ لَيْسَتْ بِمَالٍ وَأَرْمِي عَلَيْهَا فِي سَبِيلِ اللَّهِ لَآتِيَنَّ رَسُولَ اللَّهِ ﷺ فَلَأَسْأَلَنَّهُ فَأَتَيْتُهُ فَقُلْتُ يَا رَسُولَ اللَّهِ رَجُلٌ أَهْدَى إِلَيَّ قَوْسًا مِمَّنْ كُنْتُ أُعَلِّمُهُ الْكِتَابَةَ وَالْقُرْآنَ وَلَيْسَتْ بِمَالٍ وَأَرْمِي عَلَيْهَا فِي سَبِيلِ اللَّهِ قَالَ «إِنْ كُنْتَ تُحِبُّ أَنْ تُطَوَّقَ طَوْقًا مِنْ نَارٍ فَاقْبَلْهَا»
