عَنْ عُتْبَةَ بْنِ الْمُنْذِرِ قَالَ: كُنَّا عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَرَأَ: (طسم) حَتَّى بَلَّغَ قِصَّةَ مُوسَى قَالَ: «إِنَّ مُوسَى عَلَيْهِ السَّلَامُ آجَرَ نَفْسَهُ ثَمَانِ سِنِينَ أَوْ عَشْرًا عَلَى عِفَّةِ فَرْجِهِ وَطَعَامِ بَطْنِهِ» . رَوَاهُ أَحْمد وَابْن مَاجَه

‘Ubada b. as-Samit told that he said, “Messenger of God, one of those whom I have been teaching the Book and the Qur’an has presented me with a bow, and as it cannot be reckoned property may I shoot with it in God's path?" He replied, “If you want to have a necklace of fire put on you, accept it." Abu Dawud and Ibn Majah transmitted it.
