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

‘Utba b. al-Mundhir said that once when they were with God’s Messenger he recited Ta’ Sin Mim (Al-Qur’an 28. The passage about Moses hiring himself is verses 26 to 28) till he came to the story of Moses and said, “Moses hired himself for eight or ten years in return for preserving his chastity and receiving his food." Ahmad and Ibn Majah transmitted it.
